Svetlana Troitskaya (DevExpress) — Tue, 25 Aug 2026 02:05:00 Z

The features/capabilities we expect to ship in our next major update apply to both DevExtreme JavaScript component libraries (Angular, React, Vue, jQuery) and DevExtreme-based ASP.NET MVC/Core controls.

To help us fine tune our release plans, please respond to the survey questions embedded within this post. Alternatively, submit a support ticket via the DevExpress Support Center. We will be happy to follow up.

The information contained within this Roadmap details our current/projected development plans. Please note that this information is being shared for INFORMATIONAL PURPOSES ONLY and does not represent a binding commitment on the part of Developer Express Inc. This roadmap and the features/products listed within it are subject to change. You should not rely on or use this information to help make a purchase decision about Developer Express Inc products.

Roadmap Updates

This roadmap will be updated regularly to reflect development progress. As we near our official release, we expect to add additional items and modify the status of planned features as necessary. Look for the following labels next to each feature:

Planned - Feature is scheduled but not yet in development.
In Development - Under active development.
Released in Beta v26.2 - Will be available in our v26.2 beta release.
Released in v26.2 - Fully implemented and available in v26.2.

DevExtreme AI Agent Skills — Planned Enhancements

All Platforms
In Development

In v26.1, we published a set of AI Agent Skills for DevExtreme. These skills help AI coding agents generate higher-quality code that adheres to DevExtreme APIs, patterns, and best practices.

We expect to improve these skills in upcoming release cycles. Planned updates include:

Improvements to existing skills
New skills for additional components and usage scenarios
ASP.NET Core support

Security — SBOMs and CRA Readiness

All Platforms
Planned

If you deliver software in the EU, the Cyber Resilience Act (CRA) will require a Software Bill of Materials (SBOM – an inventory of every component inside your solution) as part of your conformity documentation. The CRA and its associated regulatory regime will go into effect on December 2027. Each software application/solution manufacturer must fulfil SBOM-related obligations. DevExpress-authored SBOMs will help customers document/inventory DevExpress libraries used within a DevExpress-powered app.

Most dependency scanners and SBOM generation tools read what a NuGet package declares (its dependencies on other NuGet packages) and stop there, which leaves two gaps we fill:

Components embedded inside a package. Some DevExpress NuGet packages bundle fonts and third-party JavaScript libraries. Package metadata has no way to declare them, so a scanner never reports them — even though their licenses and vulnerabilities are as real as those of any declared dependency.
Developer dependencies. Libraries we use to build our products never reach users, so we mark them with scope: "excluded". We list these libraries regardless, because all vulnerabilities should be documented.

We released a preview version of DevExpress-authored SBOMs in May 2026 (for our .NET NuGet packages). SBOMs for CRA Compliance in DevExpress-powered Apps describes what the files contain and how to feed them into tools such as Dependency-Track, Trivy, and Grype. With v26.2, we expect to extend coverage to NPM packages and DevExpress VCL libraries, take our SBOMs out of preview and make them available to every customer.

DataGrid Enhancements

Semantic Search

All Platforms
In Development

v26.2 will introduce a new DevExtreme DataGrid Semantic Search option – one that integrates the component with an AI-powered semantic search backend. Semantic search uses AI embeddings to locate data records based on meaning rather than exact wording. To filter date, the backend processes the context and intent behind a question or phrase.

Semantic search is perfect for unprocessed/uncategorized data sets (where configuring filters for exact values may be tedious). By using longer/specific queries, this option can help users locate records more effectively. To control search precision, users will be able to fine-tune search results using a similarity factor.

Semantic search requires resource-intensive data vectorization. This process is best suited for the server-side, especially for large data sets with records in the tens of thousands. We will demonstrate how to implement semantic search using an ASP.NET Core backend that is tailored to the DevExtreme DataGrid. The UI component itself will require minimal configuration on the client side.

AI-powered Detail View

All Platforms
In Development

We expect to add AI-driven data analysis for those using our DataGrid's master-detail view. This new option will allow users to interrogate individual records using natural language.

In v25.2, we added an AI column to our DataGrid. This feature helped analyze component data using an AI prompt. While valuable, certain usage scenarios do not require generated data for every row. Instead, users may need on-demand data generation for specific rows. Our new AI detail scenario will offer this capability, which can significantly reduce AI token consumption and enhance data generation performance.

Our new AI master-detail feature will also display generated content in a format better suited to longer, more in-depth insights. This option will include a prompt-driven data analysis UI within the DataGrid’s master-detail interface, spanning the full width of the component.

Within the detail row, users will be able to ask questions about the active record and receive AI-generated insights. The AI assistant will be able to summarize record data, clarify complex values, highlight notable patterns, and obtain contextual information specific to the active record.

This option is particularly valuable for data-intensive applications where records contain many fields or complex business information. Instead of searching through multiple columns and analyzing data manually, users can obtain necessary information using a natural-language prompt. This will improve both user productivity and your application's overall user experience.

DevExtreme Chat — Tool Call Visualization

All Platforms
In Development

We expect to add the ability to display AI tool/function calls in the DevExtreme Chat message body. These tools/functions can be declared locally within the app or available via MCP servers.

This visualization will increase clarity and transparency. Chat users will be able to see which tools were used, their order, and parameters alongside the AI response.

DevExtreme Scheduler — Hierarchical Resource Grouping

All Platforms
In Development

DevExtreme Scheduler currently supports appointment grouping at a single resource level. With v26.2, we will extend this behavior with hierarchical (multi-level) resource grouping based on direct parent-child relationships in your resource data source.

Planned capabilities will include:

Multi-level (parent-child) resource grouping with unrestricted nesting depth
Nested row headers for Timeline view and nested column headers in Day/Week views (both vertical and horizontal grouping)
Appointment rendering in the correct leaf resource while preserving existing appointment drag-and-drop behavior

This capability is especially valuable for applications that schedule appointments across layered resource hierarchies, such as departments and employees, buildings and rooms, or teams and equipment. You will be able to define parent-child relationships between resources and control which child resources belong to each parent, creating a clear and intuitive hierarchy.

DevExtreme Map — OpenStreetMap (OSM) Support

All Platforms
In Development

We expect to add OpenStreetMap (OSM) support to the DevExtreme Map component. The new provider will allow you to connect the Map to OSM-compatible tile, geocoding, and routing services, including commercial providers and self-hosted infrastructure.

Planned capabilities will include:

Support for core Map features, including markers, routes, and tooltips
Additional configuration options for OSM-based services
Greater control over service selection, deployment model, and mapping infrastructure

Globalization – Separate Text and Date/Number Locales

All Platforms
In Development

With v26.2, you will be able to specify different locales for application text values and dates/numbers. You will be able to change languages without affecting date/number formatting and vice versa.

Accessibility

All Platforms
In Development

We expect to improve accessibility for the following DevExtreme UI components:

Our long-term goal is to address all limitations identified in our DevExtreme Accessibility Conformance Reports (ACRs).

DevExtreme PivotGrid — Keyboard Navigation and ARIA Attribute Updates

All Platforms
In Development

With v26.2, we expect to improve PivotGrid keyboard navigation and ARIA semantics to support a more accessible interaction model.

Planned enhancements include:

Consistent arrow-key navigation across column headers, row headers, and area items
Keyboard access for expand icons and column sort operations
Keyboard-accessible Field Chooser content with visible focus states
Focus returned to the trigger button when a popup closes
Header filter activation from keyboard input with an aria-label that includes column context
ARIA grid semantics alignment, including header-to-data associations and aria-rowindex/aria-colindex metadata for clearer screen reader announcements
Keyboard access for scrollable regions and keyboard commands for context menus

DevExtreme Toolbar — Enhanced Keyboard Navigation

All Platforms
In Development

We expect to align "focus management" in the DevExtreme Toolbar with W3C Toolbar pattern recommendations.

Keyboard users will navigate the Toolbar with a single Tab stop and arrow keys between items, instead of tabbing through each item individually — a faster, less error-prone path through the toolbar. Items containing other components (for example, a search box) will support the same model:

Arrow keys reach the item.
Enter or Space moves focus inside the item.
Esc returns to the toolbar.

A visible outline on the focused item will allow users to track keyboard focus.

The same navigation model will extend to built-in toolbars in the following DevExtreme components:

DataGrid
File Manager
HTML Editor
Scheduler
TreeList
Rich Text Editor for ASP.NET Core
Spreadsheet for ASP.NET Core

We will also add an option to preserve behaviors within applications that require our previous implementation.

Globalize — Deprecation Plans

All Platforms
Planned

DevExtreme supports two localization/internationalization libraries: Intl and Globalize.

Globalize is currently in maintenance mode and may introduce long-term security and reliability risks. We plan to deprecate Globalize support in our next two major release cycles (v26.2 and v27.1) and remove support in subsequent releases.

We will publish migration guidance to help you transition with minimal disruption.

If you currently use Globalize, we would appreciate your feedback. Your input will help us understand real-world usage scenarios and assess the impact of this change.

ASP.NET Core

.NET 11 Support

ASP.NET Core
Planned

DevExpress ASP.NET Core controls will support .NET 11 (both v26.1 and v26.2) following Microsoft's official release.

Minimum Supported .NET and Visual Studio Versions

ASP.NET Core
Planned

As you may know, .NET 8 and .NET 9 will reach end of support on November 10, 2026. We will therefore raise our minimum supported .NET version to .NET 10 once we release v26.2 in December. The minimum .NET Framework version will remain 4.6.2.

Visual Studio 2022 will be the minimum supported IDE version when v26.2 ships.

DataGrid & TreeList — AI Assistant

All Platforms
Released in v26.1

With our v26.1 release, we will extend the AI-powered capabilities of both the DevExtreme DataGrid and TreeList. We plan to introduce a DevExtreme Chat-based AI assistant that will allow you to use natural language to interact with DataGrid/TreeList. The DataGrid/TreeList AI assistant will be able to complete the following actions:

Sort, filter, search, and group data.
Resize, reorder, fix/unfix, and show/hide columns.
Change pagination settings.

In our last release (v25.2), we introduced a standalone Speech To Text component. By incorporating this component into our Chat component (planned for 26.1), you will be able to add Speech to Text to your next DevExtreme-powered AI Assistant as well. This will eliminate the need for manual configuration and improve accessibility when working with DataGrid/TreeList (by offering an additional interface when interacting with UI elements).

This feature is particularly well suited for the following usage scenarios:

Large Datasets: Use the power of AI to browse large data sets. Apply complex filter values with natural language.
Complex Grid Configurations: Allow users to specify complex display preferences quickly.
Accessibility-first Applications: Allow users to interact with your application in a manner that is most appropriate for each specific situation: while at their desk, or on the go (when their hands are busy and they require voice commands to interact with your app).
Replicable Configurations: Apply the same prompt to recreate complex grid configurations across sessions. Reduce time spent on tedious layout adjustments.

DataGrid & TreeList — Persistent Validation Messages in Editors

All Platforms
Postponed

We expect to introduce new APIs that will allow validation messages to remain visible even when data editors lose focus (similar to the validationMessageMode='always' in components such as our TextBox). These APIs will apply to all available editing modes.

Appointment Snap Modes

All Platforms
Released in v26.1

DevExtreme Scheduler will include a new appointment snap mechanism. The following modes will be available:

always - an appointment always stretches to cell borders.
auto - an appointment is stretched to cell border only if the distance from the cell border to the edge of an appointment is less than half of the cell width.
never - appointments are proportional to their duration.

Handle Appointment Time Overlapping

All Platforms
Released in v26.1

Managing appointment overlapping will be easier with our next release. We will add public APIs to obtain an array of appointments for a specific range. You will be able to implement the following scenarios using these APIs:

Prevent Time Conflicts: Notify users about a scheduling conflict. Restrict adding, editing, or moving appointments if the selected time slot is already occupied.
Suggest Available Time Slots: Automatically suggest the nearest available time when a selected slot is unavailable.
Handle Recurring Appointment Conflicts: Detect and manage conflicts for individual occurrences within recurring appointments.
Execute Overlap Rules: Apply different overlap rules depending on the appointment category.
Enforce Buffer Time Between Appointments: Require a configurable gap before and after appointments to avoid tight scheduling.

Our long-term goal is to address all limitations identified in our DevExtreme Accessibility Conformance Reports (ACRs).

Migration Away from CommonJS

All Platforms
Postponed

As part of our ongoing modernization efforts, we will eliminate use of CommonJS. We plan to remove all CommonJS modules and imports in DevExtreme packages and source code. This change will optimize DevExtreme package size.

Please share your thoughts on this transition in the survey below. Your feedback will help us identify potential migration challenges and make the transition as smooth as possible.

Angular 22

Angular
Released in v26.1

The release of Angular 22 is planned for May 2026. As part of our commitment to same-day support for new versions, DevExtreme v26.1 will offer full compatibility once Angular 22 is available.

Changes and Future Plans: New Angular Configuration Components

Vlada Skorokhodova (DevExpress) — Mon, 07 Jul 2025 23:41:00 Z

If you've worked with the DevExtreme Angular components in the past, you likely encountered configuration components — those with dxo- and dxi- prefixes. These helper components simplify widget setup, align with Angular architectural principles, and enhance readability. They are especially useful for nested options — for example, configuring paging options for dx-data-grid using the dxo-pager component.

<dx-data-grid  [dataSource]="dataSource"> 
    <dxo-pager 
        [visible]="true" 
        [showPageSizeSelector]="true" > 
    </dxo-pager> 
</ dx-data-grid>

They are also useful for setting up collection elements, such as defining toolbar items in dx-toolbar using its child components like dxi-item.

<dx-toolbar> 
    <dxi-item location="before" widget="dxButton" > 
    </dxi-item> 
</dx-toolbar>

Let's take a closer look at how the legacy Angular configuration components work, focusing on dxi-item as an example. This component is "universal". It is used not just within dx-toolbar, but also in many other DevExtreme components (such as Form and List).

While this approach offers consistency (the same component can be used in multiple places), it does have drawbacks. dxi-item requires entirely different sets of options depending on the parent component, complicating precise typing.

The following screenshot illustrates how an IDE presents the same general property list for dxi-item in two different contexts. For instance, the expected properties for a form’s group item differs significantly from those used in a Gantt chart’s context menu item.

One of our main priorities is delivering full and robust TypeScript support. We're committed to ensuring that all DevExtreme components are strictly typed and follow modern TypeScript practices. This approach improves code completion in IDEs, allows early error detection, and increases confidence during refactoring.

As you might expect, enforcing strict typing in configuration components has proven to be a complex challenge. Adjusting typings for existing dxo- and dxi- components can affect many projects, potentially requiring significant changes after an upgrade to a new version of DevExtreme. Furthermore, the generic nature of our current configuration architecture makes it difficult to achieve the desired level of type precision.

New Configuration Components: What's Changed and Why It Matters

With DevExtreme v24.2, we introduced a new set of configuration components (built from the ground up). New components are strictly typed, can be seamlessly integrated into Angular applications, and were designed to improve the overall developer experience.

Each UI component ships with its own dedicated set of configuration components. This marks a major step forward in predictability and type safety. Here's what's changed and how it benefits you:

Clearer and More Context-Aware Configuration Components

Configuration component names now include their parent component's name. This improves code readability, prevents naming collisions, and makes templates more self-explanatory.

For example, dxi-item is now:

dxi-toolbar-item in dx-toolbar
dxi-form-item in dx-form
dxi-context-menu-item in dx-context-menu

This naming convention helps IDEs recognize component context and gives developers a clearer view of the structure, making complex configurations easier to navigate and maintain.

Strict Typing and a Better Developer Experience

New configuration components now include only the properties that are relevant to their specific parent component. This eliminates instances wherein the IDE suggests a long, generic list of unrelated options. For example, dxi-data-grid-column reveals only properties applicable to DataGrid columns. As a result, IDE suggestions are now far more accurate and useful:

Most new configuration properties are strictly typed, and others will be typed in the future. This means that any misuse of a component's API will be caught during compilation (long before it can cause issues at runtime).

What's Next: Full adoption of the new configuration components

New configuration components have significant advantages over the old architecture: they are robust, modern, error-resistant, and better aligned with TypeScript's type system. We are planning a phased transition of our entire DevExtreme Angular ecosystem to this new configuration model. To ensure a smooth and predictable migration for users, please consider the following timeline/key milestones:

DevExtreme v25.1 Release

We will start updating all demo examples and help topics to use our new model.
We officially recommend that all new Angular applications adopt our new configuration model from the start.
All features introduced in the v25.1 release require new configuration components.

DevExtreme v25.2 Release

Using legacy configuration components will trigger deprecation warnings, indicating that these components are obsolete.
The legacy configuration system will no longer be updated with new features. As a result, any new functionality introduced in 25.2 and future releases will require the use of new configuration components.
We will provide documentation, migration guidelines, and helper tools to make the transition to our new architecture as smooth as possible.

DevExtreme v26.1 Release

We will continue to support those users migrating to our new configuration components. Our goal is to ensure that everyone has the resources and guidance needed to complete the transition smoothly.

DevExtreme v26.2 Release

All legacy configuration components will be removed from our codebase.

Again, our goal is to make the transition as clear, manageable, and secure as possible. We will provide plenty of time, tools, and guidance to support this change.

We believe that strict typing is not just a trend — it's essential for scalable, predictable, and safe development. As always, we welcome your thoughts, comments, and suggestions:

DevExtreme JS & ASP.NET Core — Early Access Preview (v25.1)

Vlada Skorokhodova (DevExpress) — Mon, 21 Apr 2025 06:32:00 Z

UPDATE: What's New in DevExtreme v25.1

Our next major release (v25.1) is just a couple of months away. Here's a look at new features/capabilities included in our Early Access Preview (EAP) build (the EAP is available to active DevExpress Universal or DXperience subscribers). As always, if you discover issues with our EAP build, please submit a support ticket at the DevExpress Support Center or use the embedded survey to submit direct feedback.

Installation

If you own an active Universal or DXperience subscription, you can download our EAP build via the DevExpress DownloadManager or appropriate NuGet packages.

To begin using the DevExtreme v25.1 EAP build, simply install target framework related NPM packages (marked with the 25.1-next tag). Use one of the following commands to proceed:

npm install devextreme@25.1-next --save-exact 

npm install devextreme-angular@25.1-next --save-exact // Angular installation

npm install devextreme-react@25.1-next --save-exact // React installation

npm install devextreme-vue@25.1-next --save-exact // Vue installation

Early Access and CTP builds are provided solely for early testing purposes and are not ready for production use. This build can be installed side by side with other major versions of DevExpress products. Please backup your project and other important data before installing Early Access and CTP builds.

Early Access Preview build is considered pre-release software, and you will see a W0022 error in your browser console.

This EAP may not include all features/products we expect to ship in our v25.1 release cycle. As its name implies, the EAP offers an early preview of what we expect to ship in two months.

New Stepper Component

All Frameworks

Our Early Access Preview includes a new Stepper UI component. DevExtreme Stepper displays progress as users move through a sequence. It's ideal for multi-step processes, such as populating forms, onboarding, or app wizards.

DevExtreme Stepper supports the following capabilities/options:

DataSource integration
Horizontal or vertical layout
Navigation modes (step through sequentially or skip)
Pre-selected steps
Custom icons or text for step indicators
Step titles
Visual step validation
Optional and disabled steps
Keyboard navigation
Internationalization (right-to-left)

You can specify whether Stepper is horizontal or vertical using the orientation property. Change navigation mode to linear or non-linear using the linear property. Preselect an item by index using the selectedIndex option. The selectOnFocus option determines if items are selected automatically when focused via the keyboard.

You can customize each step using the following settings:

icon: sets an icon inside the step indicator.
text: incorporates text within the step indicator.
title: places a caption next to the step.
isValid: visually indicates validation state.
optional: visually marks as optional.
disabled: disables the step.
hint: adds an in-browser hint.

Example: jQuery.

If using Angular to evaluate/test our EAP, we recommend the use of our new configuration components:

<dx-stepper> 
    <dxi-stepper-item text="1"></dxi-stepper-item> 
    <dxi-stepper-item text="2" [optional]="true" ></dxi-stepper-item> 
    <dxi-stepper-item icon="gift"></dxi-stepper-item> 
</dx-stepper>

Scheduler – Toolbar Customization

Angular, React, jQuery, Vue

This EAP introduces a customizable toolbar to the DevExtreme Scheduler (available for Angular, React, jQuery, and Vue). This new capability can be used to add custom items like a Today button, a new appointment button, or a custom resource selector to our built-in toolbar.

Specify the toolbar property to include desired items. You can set the location for each item (much like our standalone Toolbar). For DevExtreme components, specify associatedoptions. To introduce unique elements, use a custom template.

$('#scheduler').dxScheduler({ 
    // ... 
    toolbar: { 
        items: [ 
            // DevExtreme components: dxButton 
            { 
                location: 'before', 
                locateInMenu: 'auto', 
                widget: 'dxButton', 
                options: { 
                    text: 'Today', 
                    stylingMode: 'outlined', 
                    type: 'normal', 
                    onClick() { 
                        scheduler.option('currentDate', new Date()); 
                    }, 
                }, 
            }, 
            // Predefined toolbar's elements 
            'dateNavigator', 
            // Custom element 
            { 
                template: '<div>Custom Item</div>', 
            }, 
        ] 
    } 
});

Predefined items include "dateNavigator" and "viewSwitcher". If you do not specify the toolbar explicitly, the default toolbar with these two items is displayed on-screen.

You can also switch button order used in the “dateNavigator” and decide which buttons to display on-screen.

toolbar: { 
    items: [ 
        { 
           location: 'before', 
           name: 'dateNavigator',   
           options: { 
               items: ['dateInterval', 'prev', 'next'],   
           }, 
        }, 
    ] 
}

The example below also demonstrates use of DevExtreme Button (switch to Today) and SelectBox (choose resources) in the toolbar.

Example: jQuery.

If using Angular to test our EAP, you must use our new configuration components when working with toolbar items:

<dxo-scheduler-toolbar> 
    <dxi-scheduler-toolbar-item  
        name="dateNavigator"  
        location="before"  
        [options]="{items: ['dateInterval', 'prev', 'next']}"> 
    </dxi-scheduler-toolbar-item> 
</dxo-scheduler-toolbar>

Map – Custom Route Modes

All Frameworks

With this EAP, DevExtreme Map allows you to set custom route options for various transportation types.

Azure map 'car' route mode:

Azure map 'truck' route mode:

Note that each Map provider (Azure, Google, Bing) has its own set of route modes. Pass a string with the desired route name to the routes[].mode property to test this feature. For instance, you can switch default 'car' route type in Azure maps to a custom route mode like 'bicycle' or 'truck'.

Create React Applications with Vite

React

Previously, DevExtreme CLI used create-react-app (CRA) as a build tool for React applications. In February 2025, CRA was deprecated. With this EAP, we switched from CRA to Vite when creating DevExtreme React applications.

When creating a new app, DevExtreme CLI now allows you to choose between JS transpilers: Babel (used previously as the default) and SWC. To test this capability, select transpiler type in a terminal:

Or you can add a --transpiler=swc or --transpiler=babel argument to the first command:

npx devextreme-cli@1.11.0-alpha.0 new react-app app-name --transpiler=swc 

or 

npx devextreme-cli@1.11.0-alpha.0 new react-app app-name --transpiler=babel

After creating a project, run the following commands:

cd app-name  
npm run dev

In addition to Vite, we plan to add an option for Next.js build in our official v25.1 release.

DevExtreme – Create Flexible Layouts with the DevExtreme Splitter Component

Vlada Skorokhodova (DevExpress) — Mon, 10 Mar 2025 00:10:00 Z

When building an app, static layouts may not be enough. By using a "splitter" component, you can convert static page layouts to one that adapts to the needs of each individual user.

As you'll soon see, the DevExtreme Splitter UI component was designed to split a page layout into multiple resizable panes (page sections).

In this blog post, I'll explore a simple yet highly popular layout-related use case: resizing layout "sections" to display more business data (and of course, I'll be using the DevExtreme Splitter to do so). Below is the final page layout. Click the gif to see it in full screen:

Select one of the following supported dev frameworks to test the example:

Angular | React | Vue | jQuery

Implementation Details

The DevExtreme Splitter divides a layout into panes. These panes can be configured with the following basic settings:

Option	Description	Default value
resizable	Users can modify pane size.	`true`
collapsible	Users can collapse the pane.	`false`
size	Initial pane size.	`undefined`
minSize	Minimum pane size.	`undefined`
maxSize	Maximum pane size.	`undefined`
collapsedSize	Pane size when collapsed.	`undefined`

DevExtreme UI components rely on Item declarations for nested configurations (including panes). To include a component in a Splitter pane, you’ll need to create a separate template or use the following method (declare directly using Item markup).

<Splitter onResize={onResize} id="splitter" height="auto"> 
    <Item minSize={250}> 
        <DataGridComponent ref={grid} /> 
    </Item> 
    <Item minSize={250} size="55%"> 
        <ChartComponent /> 
    </Item> 
</Splitter>

This example adds the DevExtreme DataGrid and Chart components to the pane.

In this particular instance, users can view hidden DataGrid columns by expanding the Splitter's leftmost pane. For DataGrid adaptive mode, enable the columnHidingEnabled option. Call the updateDimensions method within the onResize function to adapt container size changes (for additional information in this regard, please refer to our Adaptability help topic).

const onResize = useCallback(() => { 
    cancelAnimationFrame(animationRefFrame.current); 
    animationRefFrame.current = requestAnimationFrame(() => 
        grid.current.instance().updateDimensions() 
    ); 
}, [grid]);

Customize Splitter Appearance

Once you set up a pane layout, our Splitter displays separator bars between panes. You can customize this visual element to match relevant design requirements.

For instance, you can modify separator bar width in pixels. You can also modify component appearance with custom CSS rules.

For this sample, we used custom CSS to modify both the Splitter and its panes:

// modifies the Splitter separator bar: 
.dx-resize-handle { 
    border-radius: 50px; 
} 

// rounds the corners of the pane content: 
.dx-datagrid-headers.dx-datagrid-nowrap.dx-bordered-top-view { 
     border-radius: 8px 8px 0 0 !important; 
} 
.dx-gridbase-container > .dx-bordered-bottom-view { 
     border-radius: 0 0 8px 8px !important; 
}

As the following image illustrates, you can personalize the Splitter separator as requirements dictate (through settings, CSS styles, etc).

UI Templates for Additional Layout Strategies

This sample layout was inspired by the DevExtreme UI Template Gallery. Our UI Template Gallery (for Angular, React, and Vue) includes app templates for a variety of page layouts/usage scenarios including the following:

Planning

Dashboards

Authentication forms

User profiles

Whether you're building a customer management system, a project planning tool, or user authentication flows, UI templates provide a solid foundation that you can easily modify to address specific business requirements.

DevExtreme — June 2025 Roadmap (v25.1 - Angular, React, Vue, jQuery & ASP.NET Core)

Vlada Skorokhodova (DevExpress) — Fri, 21 Feb 2025 03:10:00 Z

UPDATE: What's New in DevExtreme v25.1

In this blog post, I’ll describe DevExtreme-related features/capabilities we expect to ship in our upcoming mid-year release (v25.1). Should you have any questions about the new products we expect to ship in June or if you’d like to discuss enhancements planned for v25.1, please submit a support ticket via the DevExpress Support Center. We’ll be happy to follow up.

New Components

CardView

In our next major update (v25.1, set for release in June 2025), we expect to ship our new CardView UI component. As you can see in the following image, you can use the DevExtreme CardView to display business data using a "card" UI metaphor (a visually engaging alternative to traditional grid views).

The DevExtreme CardView will ship with the following built-in data management capabilities:

Sorting
Paging
Column reordering
Column visibility control
Editing
Filtering
Searching
Data selection

Each card within the CardView will be fully customizable, with UI elements such as toolbars, covers, and footers (allowing you to adapt layouts as requirements dictate).

CardView card layouts will be fully responsive, will support multiple screen sizes, and will ship with two layout options:

Automatic Layout: The CardView will determine the optimal number of cards per row and associated size. When resized, the CardView will dynamically modify its layout, recalculating the number of cards per row and their dimensions.
Fixed Number of Cards per Row: You will be able to specify the exact number of cards displayed within a layout. When resized, card sizes will change but the number of cards per row will remain the same.

Stepper

v25.1 will also ship with a new Stepper UI component. As you can see in the following image, our Stepper can be used to describe/detail progress as users navigate through a defined sequence. Stepper will work especially well for multi-step processes like filling forms, onboarding flows, or wizards.

You will be able to customize the appearance of individual steps and modify component settings to address specific usage scenarios.

AI-powered Extensions

In our last major update (v24.2, released Dec 2024), we began work on key AI Integrations. As you may know, part of these integrations included the release of the DevExtreme Chat UI component.

In our next release, we will incorporate AI-powered text editing into the DevExtreme HTML Editor. Users will be able to apply actions to selected content (such as proofreading, summarizing, expanding text, etc) and you will be able to add a custom command to execute a specific request to your selected AI service.

Our new AI-powered Extensions will be accessed through a dedicated button in the HTML Editor’s toolbar.

Chat Enhancements

Editing and Deleting Messages

We expect to update our Chat UI component in our next major update and allow users to edit/delete messages once they’ve been sent.

DevExtreme Chat is a client-side component that requires a backend solution. Message editing and delete operations will include relevant UI elements for end users and APIs to modify rendered messages. To edit and remove messages from a data source, you will need to use Push APIs.

Image Rendering

In v24.2, the DevExtreme Chat component shipped with custom message content support, including charts and images. To use this feature, you were required to override the entire message bubble layout using the messageTemplate property.

With v25.1, we will simplify configuration when displaying images within messages.

You will be able to easily render an image received in responses. For example, if you use DALL-E or a similar AI service to generate pictures, you can set up image rendering using our Chat component.

Scheduler – Toolbar Customization

In v25.1, the DevExtreme Scheduler will include a customizable integrated toolbar.

Configuration options will include:

Choosing from predefined elements: Select and arrange built-in elements as needed.
Adding DevExtreme components: Include and configure DevExtreme components like Button or Checkbox in the toolbar.
Inserting custom elements: Define templates for custom elements within toolbar items for a curated experience.

For instance, in the screenshot below, our new toolbar includes two custom buttons: "Today" and "New event".

Map – Custom Route Modes

DevExtreme Map will allow you to define custom route modes for different transportation types. Each Map provider (Azure, Google, Bing) offers unique predefined route modes. You will be able to specify the desired route type as a string, and DevExtreme Map will display it accordingly.

For instance, in addition to a standard 'car' route in Azure maps, you will be able to define custom route modes like 'bicycle' and 'truck'.

Azure map 'car' route mode:

Azure map 'truck' route mode:

Accessibility

We expect to address a range of accessibility issues in both the DevExtreme DataGrid and Scheduler.

DevExtreme CLI

Create a Standalone Angular Application

Angular introduced standalone components in v14. In v19, default components created with Angular CLI are now standalone. To match this trend, we will transition from modules to standalone components in DevExtreme CLI Angular applications.

Create React Applications with Vite and Next.js

As you may already know, the create-react-app (CRA) utility - a key resource for React projects - was recently deprecated. With DevExtreme v25.1, you will be able to select between Vite and Next.js (as alternatives to CRA) when creating a React application using DevExtreme CLI. Whether you need Vite’s speed and simplicity or Next.js’ advanced features and scalability, this update will offer more options to match your project’s requirements.

ASP.NET Core

Rich Text Editor – Zoom

ASP.NET and Blazor Subscription

Our Rich Text Editor's built-in Ribbon will include a UI to specify zoom level for the current document.

It will also be possible to control the current zoom level and its maximum/minimum values using the Rich Text Editor's API.

Your Feedback Matters

DevExtreme React — Gatsby and Next.js

Vlada Skorokhodova (DevExpress) — Thu, 17 Oct 2024 03:43:00 Z

We recently updated the following Gatsby/Next.js-related help topics on our website.

DevExtreme React + Next.js

Next.js allows you to choose between Server-Side Rendering (SSR), Static Site Generation (SSG), and client-side rendering. As such, Next.js is an ideal framework for sites that include both static and dynamic content (such as e-commerce sites or dashboards).

DevExtreme JS & ASP.NET Core — Early Access Preview (v24.2)

Vlada Skorokhodova (DevExpress) — Thu, 19 Sep 2024 00:00:00 Z

UPDATE: What's New in DevExtreme v24.2

Our next major release (v24.2) is a couple of months away. In this post, I'll detail new features included in our Early Access Preview (EAP) build (for active DevExpress Universal or DXperience subscribers). As always, if you encounter issues with our EAP build, feel free to submit a support ticket via the DevExpress Support Center or use the embedded survey to send us feature/product-related feedback.

Installation

If you own an active Universal or DXperience subscription, you can download our EAP build via the DevExpress DownloadManager or appropriate NuGet packages.

To begin using the DevExtreme v24.2 EAP build, simply install target framework related NPM packages (marked with the 24.2-next tag). Use one of the following commands to proceed:

npm install devextreme@24.2-next --save-exact 

npm install devextreme-angular@24.2-next --save-exact // Angular installation

npm install devextreme-react@24.2-next --save-exact // React installation

npm install devextreme-vue@24.2-next --save-exact // Vue installation

Early Access Preview build is considered pre-release software, and you will see a W0022 error in your browser console.

This EAP may not include all features/products we expect to ship in our v24.2 release cycle. As its name implies, the EAP offers an early preview of what we expect to ship in two months.

New Chat Component

All Frameworks

Our Early Access Preview ships with the first iteration of the DevExtreme JavaScript Chat component (allowing you to introduce peer-to-peer/chat-bot support within your DevExtreme-powered web application).

Key features included in the DevExtreme Chat component EAP build include:

Accept and report new messages.
Custom avatar support (initials used by default).
Sends messages using the "Send" button or Enter key.

Note: DevExtreme Chat is a client side library. An independent backend solution will be necessary. For an example of DevExtreme Chat and AI integration, refer to the DevExpress Reporting EAP blog post.

Select one of the following supported dev frameworks to explore the capabilities of the new DevExtreme JavaScript Chat component:

Angular | React | Vue | jQuery

Data Grid/Tree List — Sticky Columns

All Frameworks

The DevExtreme DataGrid and TreeList ship with fixed column support (as you know, fixed columns allow you to pin a column to the right or left side of a table/tree hierarchy).

In this EAP, a new (sticky) value is available for the fixedColumn property. Sticky columns are initially fixed but move with the table once scrolled to a specific position.

Note: This feature is still under development, and some DataGrid/TreeList features (such as resizing, reordering, or data grouping) may not work as expected.

We also redesigned our original “fixed column” engine (we now offer advanced CSS positioning).

Select one of the following supported dev frameworks to explore the capabilities of our new Sticky Columns feature:

DataGrid

Angular | React | Vue | jQuery

TreeList

Angular | React | Vue | jQuery

Tabs/TabPanel/List — onSelectionChanging Event

All Frameworks

DevExtreme Tabs, TabPanel, and List share a common feature: selectable items.

Currently, these components include an onSelectionChanged event that triggers once selections are finalized and the selectedItems option updates. This timing can make it difficult to control selection changes based on user interaction.

This EAP includes a new onSelectionChanging event for the aforementioned component libraries. The event helps track selection changes more effectively (for example, you can now prevent selection) and includes a cancel property, which can be Boolean or a JS Promise.

A common usage scenario is asynchronous validation for The Form component within an open tab. When attempting to switch to a different tab (and depending on validation results), our customers wanted the ability to either prevent tab switching or allow it. With our new onSelectionChanging event and an API that supports promises, this scenario can be implemented quite easily.

Select one of the following supported dev frameworks to explore the capabilities of the new onSelectionChanging event feature:

Angular | React | Vue | jQuery

DataSource — Case Sensitive Filtering

All Frameworks

DataSource can sort and filter data by locale, including special characters such symbols with diacritics (by using langParams options).

In this EAP, we added case sensitivity within langParams options. As you can see in the image below, you can now introduce case-aware filtering within DevExtreme UI components like our DataGrid.

This EAP also refines filtering for various locales (the filter is now more precise).

Select one of the following supported dev frameworks to explore the capabilities of our new Case Sensitive Filtering feature:

Angular | React | Vue | jQuery

Angular — New Configuration Components

Angular

This EAP includes new devextreme-angular configuration components.

As you may know, DevExtreme Splitter uses a generic dxi-item configuration component. This same dxi-item appears in components such as Form and TabPanel (causing potential confusion, especially with IntelliSense).

Our new components are specific to each parent. For instance, Splitter now also uses dxi-splitter-item, which only includes properties relevant to Splitter.

Similarly, other DevExtreme components use new configuration components that include parent name.

Note: You can either use new components or the previous, but not both.

Angular — Service for Popup Open Operations

Angular

In previous builds, you had to use a template to specify Popup content. This EAP introduces a new approach for this specific requirement. Use DxPopupService and its open method as necessary (this method takes a content component and a Popup configuration object).

import { DxPopupService } from “devextreme-angular/ui/popup”; 
// ... 
constructor(private popupService: DxPopupService) 
// ... 
popupService.open(ContentComponent, { showCloseButton: true })

The open method returns both Popup and contentComponent instances. In the following example, these instances are used to close the Popup programmatically:

Demo

.NET

.NET 9 Support

The DevExtreme product line now supports NET 9 RC1 .

.NET 8, .NET Framework 4.6.2, Visual Studio 2019 Will Be Minimally Supported Versions for DevExpress Libraries (v24.2+)
