WPF Controls - 2019 Roadmap - Your Vote Counts

WPF Team Blog
25 December 2018

It’s that time of year – time to reflect on accomplishments and prepare for the upcoming year. Thanks to your great feedback, we’ve compiled a list of features we hope to deliver this year. Though this list is not yet final, we do want to share it with you and solicit additional feedback.

Please note that this is not an all-inclusive list of features for 2019. If you are interested in our plans for DevExpress Office-inspired libraries (RTF, Spreadsheet), the DevExpress Reporting platform, or our Analytics tools, please refer to the appropriate blog post for more information:

  1. Office File API, Office-inspired Desktop UI Controls
  2. WinForms and WPF Reporting
  3. WinForms, WPF and ASP.NET Charting
  4. WinForms and WPF Diagram

.NET Core 3 Support

We've just released v18.2.4 that supports the Preview 1 version of .NET Core 3 (see Visual Studio 2019 and .NET Core 3 Support). Throughout 2019, .NET Core 3 will remain a primary focus area. Together with Microsoft, we will work on known issues and change our control implementation where necessary. Our goal is to provide you with a stable and well-tested component set by the time .NET Core 3 is released.

New Controls


We will be working on a new Breadcrumb control in 2019. It will help simplify app navigation and allow you to construct hierarchical navigation paths.

The Breadcrumb’s API will generate data on the fly and will support data binding.

Time Picker

Our new Time Picker control will allow you to edit time values. It will be a standalone control that can also be integrated into our existing DateEdit.

TimeSpan Editor

TimeSpanEdit is a text box that allows you to edit TimeSpan values (duration). You will be able to use it as a standalone editor or within container controls such as the DevExpress WPF Data Grid and WPF Gantt.

We have yet to finalize plans for the TimeSpanEdit control and are not certain whether it will ship with a dropdown (in addition to a text box). Let us know whether you’d like to see a dropdown for this control in the comments section.

Data Grid & Tree List – Common Features

New Filter Panel

We hope to improve the DevExpress WPF Filter Panel to make it more intuitive and easier to use. Currently, it displays a string representation of applied filters (as plain text). This approach works well for simple filters with one or two filter clauses. Complex filters are hard to read and will be truncated if they don’t fit on-screen. The new Filter Panel will display separate tokens with filters for every column (making it easier to read and manage).

If an applied filter does not fit within the screen area, tokens will be collapsed and will display detailed information in a popup. 

Filter Editor – New Design, Customization API, and more

In our v18.2 release cycle, we released a new Filter Editor. We plan to extend and improve this control in 2019 with the following features:

  • A hierarchy for bands or nested properties in the field selector.
  • Advanced customization API.
  • Support for Aggregate operations (e.g., "Accounts.Sum(Amount) < 100").

We will also modify the Filter Editor’s appearance and give it a more modern look & feel:

Once these enhancements are complete, we will use the new Filter Editor in the Pivot Grid and DevExpress Reports.

Grouped Filters

With Grouped Filters, you will be able to display values from multiple columns in the Excel-style Filter Dropdown.

Conditional Formatting Filters

Conditional Formatting Filters will be available both in the Filter Dropdown and Filter Editor. They will allow you to filter data based on Conditional Formatting rules defined for a column.

We will also create a dedicated Filter Element for Conditional Formatting Filters.

Search Enhancements

The Search Panel will display the total number of matches and the index of the current match. We will rework the Search Panel’s buttons to make them more compact.

We have some ideas for search performance optimization. If all goes well, the search will work significantly faster in grids with many columns and rows.

“No Records” Text Block

This is a small but often requested feature – the Data Grid and Tree List will display a text block in the data area when it displays no records, or if a filter/search query yielded no results.

Data Grid

Master-Detail Search

The Search Panel in the master grid will search and filter data in all detail grids as well. You will be able to navigate between matches in both master and detail records to quickly locate information.

Tree List

New Item Row

The WPF Tree List will display an additional empty row at the top or bottom. You will be able to enter data into the empty row to create new nodes and then drag them anywhere in your hierarchy.

New Filter Mode

With our new filter mode, the Tree List will display all child nodes when their parent nodes meet the applied filter criteria.

IsEnabled CheckBox Binding

You will be able to disable node check boxes for specific nodes based on your business logic.

Pivot Grid

Excel-style Filter Dropdown

Our WPF Pivot Grid will support a new Excel-Style filter dropdown. It will allow you to search for filter values, select multiple values simultaneously, and display values from multiple columns in a hierarchy. You will also be able to define more complex filters for a given column using the Filters tab.

New Filter Editor

The Pivot Grid will use the new Filter Editor developed for the Data Grid. It will support all new filtering features (record count display, predefined filters, aggregate operations), will be more customizable and modern in appearance.

New Filter Panel

Like the Data Grid and Tree List, the Pivot Grid will feature a new Filter Panel that displays filter clauses for different columns as removable tokens. The new Filter Panel can collapse tokens and display more information within a dropdown.


Fluent Design – Acrylic Material and Reveal Highlight Effect

We will support the following Fluent Design elements in 2019: Acrylic material and Reveal Highlight effect. We will implement these features for our Themed Window and Hamburger Menu controls so you can deliver apps that mimic the user interface of Microsoft’s Windows 10 Mail app.

If we see enough interest for Fluent Design, we will implement the Acrylic material and Reveal Highlight effect in other Windows 10-inspired controls in the future.

Office 2019 Themes

We will release a set of Office 2019-inspired themes for our WPF UI Controls. Like other modern themes, they will ship with lightweight templates for our most popular controls and will support color palette customization in the Theme Designer.

Color Presets

Office 2019 themes will introduce a new concept to our WPF themes – Color Presets. Themes that support Color Presets will be able to switch their color scheme dynamically at runtime (much like our WinForms Bezier theme). This will allow you to use one theme with an unlimited number of color presets. It will help you extend end-users options without affecting the size of the deployed package.

For the last few years, we’ve been focused on themes inspired by popular Microsoft applications – Office and Visual Studio. Needless to say, the appearance of these Microsoft-inspired themes doesn’t leave much room for experimentation. Some of you have asked that we ship themes that look different from those found in Office and Visual Studio.  We know that the DevExpress WinForms Bezier theme was well-received and believe that certain applications can benefit from more informal themes such as Dracula. Also, we periodically get requests for themes inspired by popular design concepts – Material Design and Fluent Design. We would like to hear your opinion on themes:

Theme Designer Enhancements

Since appearance and personalization is a popular request, our team will continue to improve our Theme Designer tool. We expect to introduce the following enhancements in 2019:

  • An incremental build process that significantly reduces the time to build a theme.
  • A Command Line Interface to build your custom themes without opening the GUI.


Office 2019 Style and Simplified Ribbon

Our WPF Ribbon control will introduce a new Office 2019 style that that closely matches the Ribbon in latest Microsoft products. We will also ship a Simplified Ribbon option, allowing you to collapse the Classic Ribbon into a single row.

By default, the Simplified Ribbon will use the same set of Bar Items defined for the Classic Ribbon. You won’t need to write any additional code to use it.

Important note: Microsoft Outlook uses separate 20x20 icons for its Simplified Ribbon. Since we don’t want you to create a new set of 20x20 icons to start using our Simplified Ribbon mode, we decided to stick with 16x16 by default and use additional margins to achieve the same Ribbon size. For those of you who have 20x20 icons, we also plan to create an API that allows you to define an additional 20x20 icon for each Bar Item used in Simplified Ribbon mode.



We expect to rework our WPF Scheduler’s print functionality. This will include a new WPF Preview window, updated printing templates, customization API, and more.

Design Changes – Outlook-inspired UI

The Scheduler’s UI will change so that it is more modern and matches the user experience of Microsoft Outlook. The enhancements we hope to ship in 2019 include:

  • Resource headers will look like tabs and will use resource colors.
  • Date headers will also use resource colors and will look slightly different.
  • Appointments will use resource colors if no label is specified.
  • Navigation buttons will look different and will also use resource colors.
  • Empty cells will look the same for all resources (white in most themes).
  • We will add a header with the current date and navigation buttons at the top.

Special Slots

Special slots will allow you to define dates or time areas and highlight them on the Scheduler’s surface.

Clipboard Support

The Scheduler will support Cut, Copy, and Paste operations within one control, between controls in the same application, and between multiple applications using the Scheduler.


Automatic Task Scheduling

This functionality is crucial for proper data editing in the WPF Gantt control. Whenever you update a task or load a data source with incomplete data into the Gantt control, the Gantt control will automatically calculate Start/Finish dates for all dependent tasks. For example, you will be able to create a set of dependent tasks and define how much time is needed to complete each task. The Gantt control will then arrange tasks on the timeline and decide when each task should start and end.

Worktime Duration

The Gantt control will take non-working hours and holidays into account when calculating task duration. For example, with the default configuration, a task with a Duration of 16 hours will span two days on the timeline and will display ‘2 days’ in the tree list area.

Task Interaction

You will be able to drag-and-drop tasks to change Start Date, resize tasks to change Duration, change task Progress, and draw a line from one task to another to create a dependency.

Editing Enhancements

We will create dedicated editors for the Duration and Predecessors columns in the Tree List area so that end-users can easily enter TimeSpan values and select predecessor tasks from a dropdown list.


The Gantt control will allow you to highlight specific regions in the Gantt area to indicate an event or an important event (a weekly meeting, release date, etc).

Critical Path

The Gantt control will automatically calculate and highlight the critical path in the Gantt area. The critical path will automatically update whenever you move tasks or change duration and progress.

Dependency Lag

Every dependency will include an optional Lag value (positive or negative) that indicates the amount of time that should pass before the dependency effects a connected task.

The features listed above should address the requests you’ve submitted to us. Some of you have also asked for a Resource View - a control that displays a list of resources and task list for every resource (to help evaluate resource load).

We believe that a Resource View is a separate control. It will require significant manpower to develop. We’ve decided not to implement the Resource View for now and would like to hear your opinion. If we commit to the Resource View, we will have to cancel many tasks for other controls (for example, the Kanban Board).

Oh, DevExpress gods, you heard my long-standing prayers for a New Item Row in TreeList ...

It remains to wait for this in WinForms. I hope that I do not have to wait another 14 years.

My #1 request would be increased modularity of components, hopefully resulting is less libraries to ship and faster startup.

For example, to use DevExpress.Xpf.Ribbon, the dependency chain we need to ship with our apps includes things like DevExpress.Pdf.Core and DevExpress.Printing.Core.  It would be nice if we could ship a smaller set of dependencies based on the features we actually need.

I'm definitely interested in seeing a material theme some day. The color presets thing though would be great though. I'm hoping it allows for dark/light mode for apps so I don't have to include all these big DLLs for multiple themes for dark green/dark blue/dark red/light green/light blue/light red/ whatever else the users request. :)

I Strongly recommend you to give full support for Prism Library as Infragistics are doing. Prism is such an essential part of WPF we would like to see more from DevExpress.

I think it's great that you listen for needs of enterprise and needs of displaying data in such a way that any modern app should do. Gantts and Kanbans are real way to getting into projects, production workorders planning, etc.

All of these are great things to have and I'm really plaesed that you have our back in 2019.

Best wishes!

Best wishes and see you in 2019. It's nice that you are listening for user voice.

I like to see Windows 10 themes in our app next year :)

Thanks Alex,

great Job.

For the Gantt Control i need a manually drag and drop to other resources.

Please consider creation of "Fast & Simple" DevExpress WPF Theme.

To allow fast starting & lightweight UI updating apps.

Why? There's 50%-100% additon in startup time delay depending on used DevEx theme compared to similar app having default WPF UI controls .

Our WPF subscription comes with Prism adapters for Prism versions 5, 6, and 7. If you need something our Prism Adapters library does not offer, please contact me at wpfteam@devexpress.com and describe your scenario.

The RangeControl already provides the functionality you mentioned - see the RangeStart, RangeEnd, and IntervalFactories properties:


If these properties are insufficient, I will be happy to discuss the details via email or the Support Center.


I would like to learn more about your use case. It is possible that generating native images or using the ProfileOptimization class may improve the startup performance in your scenario:

@Alex Chuev

I forgot to ask, but just out of curiosity, do you have any plans to make a version of the Bezier theme itself for WPF in the near future?

Thanks again for your commitment to WPF. I'm really looking forward to the next release.

Most definitely a timespan editor for wpf.

I don't care for your current WPF themes, except for the VS2010 and Deep Blue themes.   I much prefer your wide selection of WinForms themes rather than any of the Office-based or Google flat themes.    Can the WinForm themes be ported to WPF?  Please don't follow Microsoft or Google as the definition of good-looking user interfaces.

First of all I want to thank you for the great job!

Please consider a better performance of file/folder open/save dialogs.

TimeSpan editor with support null values, ability to set the custom mask (for example, to edit only seconds and microseconds and other)

Themes: it would be great if DevExpress team can look into introducing a dedicated theme for high-contrast (light or/and dark) for accessibility. Right now the process is that each theme we pick needs to be customized, which is quite a tedious task that seems everyone who deal with accessible applications has to do.

We have no immediate plans for the Bezier theme. So far, we've seen that most people like the color switching functionality that the Bezier skin provides. We are currently testing how this functionality will work with our WPF themes. Another significant advantage of Bezier compared to other WinForms skins is vector elements that look good on high DPI screens. However, this advantage is irrelevant in WPF where all visual elements are scaled by the platform.

What specifically do you like about the Bezier theme and why do you think it should be ported to WPF?


Which WinForms skins would you like to see ported to WPF and why?

Implement a DateNavigator with StartDate and EndDate, as in the standard Windows WPF Calendar

15 March 2019

Our DateNavigator (docs.devexpress.com/.../datenavigator) already provides this functionality. In version 18.2, you can set its MinValue and MaxValue properties similar to DisplayDateStart and DisplayDateEnd of the standard Calendar.
