  • ASP.NET Spreadsheet - UX Enhancements and UI Performance - (Coming soon in v16.1)

    ASP.NET Spreadsheet - UX Enhancements and UI Performance - (Coming soon in v16.1)

    You'll be happy to hear that not only did we improve the performance of the DevExpress ASP.NET Spreadsheet control in the v16.1 release, but we also added some great features too. Let's take a look.

    UX Improvements

    The DevExpress ASP.NET Spreadsheet now ships with a number of improved UX elements including:

    1. Custom header/footer when printing

    A new dialog (within the page-setup dialog) gives you the ability to define a custom header and footer before printing your spreadsheet:

    2. Mark a copied range using a dotted line

    The Spreadsheet control will now use dotted lines when you select a range and copy it to the clipboard. This is a handy feature that you're likely familiar with in Microsoft Excel. It helps you to visualize what items you've just selected.

    3. Fill handle

    The Spreadsheet control now gives you the ability to use a fill handle to complete data in a series. You can even use it to fill in months and days:

    4. Display/hide column and row headers

    The Spreadsheet control also let's you hide (or show) the column and row headers.

    UI Performance Improvements

    Our ASP.NET Spreadsheet has been optimized so you can deliver Office-inspired solutions that are both visually stunning and perform at the highest possible levels. Performance optimizations have been applied across the board, at the server and during client rendering.

    Take a look the following chart which shows the 'document load' and 'cell update' operations. You'll see how between v15.2 and v16.1, we've improved performance across all major browsers:

    Azure Web Farms support

    With this release, both the DevExpress ASP.NET Spreadsheet and Rich Text Edit controls can be used in web applications running on multiple Azure application servers.

    What do you think about the Spreadsheet control's new features and performance enhancements? Drop me a line below. Thanks!

  • HTML5-JavaScript Scheduler - Agenda, Timeline Month View, and more (Coming soon in v16.1)

    2. New Timeline Month view

    3. Time Zones Support

    The DevExpress HTML5-JavaScript Scheduling widget allows you to specify a time zone:

  • HTML5-JavaScript Pivot Grid – Enhancements (Coming soon in v16.1)

    In the v16.1 release, we've added three great new features to the DevExtreme JavaScript Pivot Grid.

    1. Field Panel

    The field panel displays fields involved in summary calculation and allows to dynamically change report options (filtering conditions and sorting order) directly in the widget:

    DevExtreme Pivot Grid - Field Panel

    The field panel provides you the capability to change any field option at runtime using the context menu. You can easily reach this performing the required data calculations within the 'onContextMenuPreparing' event handler. So, you can implement a custom context menu with a collection of summary types, for example, sum, average, minimum, maximum, and etc. Also, you can specify a similar event handler for the DevExtreme Pivot GridFieldChooser widget.

    DevExtreme Pivot Grid - Runtime Summary

    2. Charts integration

    The DevExtreme Pivot Grid widget can handle processing large amounts of data easily. However, it's not easy to visualize large amounts of data. So one way to manage that is to use charts to summarize large amounts of data. And with the v16.1 release, the DevExtreme Pivot Grid can easily integrate with a chart to help you process large amounts of data and show a corresponding chart next to it!

    DevExtreme Pivot Grid - Charts Integration

    Simply pass a chart instance and additional settings for showing multidimensional data to the 'bindChart' method of DevExtreme Pivot Grid.

    3. Layout Enhancements

    Besides features mentioned above, the DevExtreme Pivot Grid widget includes some layout improvements. One of them is a tree layout mode designed for hierarchical items in a row header. By default, such items placed in row take too much space on the screen. However, using the new layout helps to optimize this area and use it more effectively.

    DevExtreme Pivot Grid - Row Header Layout

    The other new layout feature is relocatable data field header. Previously, data field headers could be displayed only in columns. Starting with the upcoming release, you can specify whether they are located in columns or rows.

  • HTML5-JavaScript TreeMap (Coming soon in v16.1)

    Check out the new DevExpress HTML5 TreeMap widget that's coming out in the DevExtreme v16.1 release:

    DevExtreme TreeMap

    The new TreeMap widget is a client-side JavaScript widget which provides powerful capabilities to display both flat and hierarchical data structures. And the TreeMap widget includes three predefined tiling algorithms:

    • Slice And Dice
    • Squarified
    • Strip
    • Or apply your own custom algorithm!

    DevExtreme TreeMap

    The new TreeMap widget provides several colorization methods of TreeMap tiles, such as discrete colorization, range, and grouped. And the widget provides API methods for drilldown implementation and manipulation of separate tiles.

    Then give us your feedback here: Issue Tracker

    What's included?

  • HTML5 - JavaScript Data Grid - Banded Column Layout (Coming soon in v16.1)

    We're introducing a great new DataGrid feature – Banded Column Layout. With this feature, you can organize columns into the logical groups (bands), so that you can easily display and reorder entire column sets.

    DevExpress HTML5 Data Grid - Banded Column Layout

    While a column is banded, all existing column features still work great:

    • Column Resizing
    • Column Reordering
    • Column Fixing
    • Column Chooser
    • Export

    In fact, here's the column chooser in a banded layout:

    DevExpress HTML5 Data Grid - Banded Column Layout - Column Chooser

    Banded Column Layout is easy to define and customize. Here's a snippet that shows how the population column from the image above is banded:

    $("#gridContainer").dxDataGrid({
        dataSource: countries,
        columnAutoWidth: true,
        allowColumnReordering: true,
        columns: ["Country", {
            headerCellTemplate: function(container) {
                container.append($("<div>Area, km<sup>2</sup></div>"));
            },
            dataField: "Area"
        }, {
            caption: "Population",
            columns: [{
                caption: "Total",
                dataField: "Population_Total",
                format: "fixedPoint"
            }, {
                caption: "Urban",
                dataField: "Population_Urban",
                format: "percent"
            }]
        }, {
            caption: "Nominal GDP",
            columns: [{
                caption: "Total, mln $",
                dataField: "GDP_Total",
                format: "fixedPoint",
                sortOrder: "desc"
            }, {

    This feature is a part of the DevExtreme v16.1 release. Thanks!

  • ASP.NET Vertical Grid Control - (Coming soon in v16.1)

    In the v16.1 release, we're introducing a new vertical grid control!

    The new DevExpress ASP.NET Vertical Grid control is based on our popular ASPxGridView control and that means you'll get powerful features and functionality built into the very first version.

    A vertical grid swaps the layout for rows and columns. So the columns that are placed at the top are now on the left. And the rows are displayed vertically. Here's a great example:

    DevExpress ASP.NET Vertical Grid

    This type of layout is great for certain types of data. For example, comparing products.

    Feature packed

    The new DevExpress ASP.NET Vertical Grid control is feature packed:

    • Large Database (Server Mode)
    • Header Filter (and other filter options)
    • Batch Editing and updating
    • Categories (allows you to group rows in category rows)
    • Conditional Formatting
    • Summaries
    • Exporting
    • Templates
    • and more features similar to the DevExpress ASP.NET GridView

    WebForms & MVC

    And I'm happy to announce that the new Vertical Grid control will be available for both ASP.NET WebForms and MVC platforms in the v16.1 release.

    Thanks!

  • Help test the new DevExpress ASP.NET Bootstrap enabled controls

    We're working on a new set of ASP.NET controls that will support Bootstrap. And I would like your help in testing these new controls. More details on that below.

    First, let's address your questions:

    Why? What problem are you solving?

    Our current ASP.NET controls are great but their HTML rendering makes it hard for us to support:

    1. Adaptive and mobile-friendly features
    2. Frameworks like Bootstrap that provide their own themes

    So to solve these main issues, we're going to keep the majority of our current ASP.NET codebase and create new (descendant) controls with new HTML rendering. This approach is great because it gives you a benefit of new controls, new rendering, and a solid codebase that they inherit from.

    This effort will take many releases before we have a full suite of controls like our existing ASP.NET controls. But in the first beta release, we'll likely have a Grid control and a few others.

    And we want your help in testing these controls. If you're interested and willing, click the link below and we'll register you for a private closed testing once we have a build ready.

    Register Now

    Why Bootstrap?

    Bootstrap is one of many great frameworks out there. And the new ASP.NET controls we're working on will make it easier for us provide support for other frameworks besides Bootstrap. We chose Bootstrap because:

    1. It's established), popular, and free
    2. It has a good ecosystem of open-source contributors, third-party themes, etc.
    3. Microsoft chose Bootstrap for their File->New experience.

    Here's a small preview of our new ASP.NET pager control using different Bootstrap themes:

    Not all controls nor features

    Creating a new line of controls also gives us a fresh start to decide which controls and features are worth it to you. So, our initial goal is to create similar versions of our major controls and features. In fact, in the beta that we would like you test, it will likely only include the new Grid.

  • IE8 support ending in upcoming v16.1 release

    In the next major release of DevExpress (v16.1), we are dropping support for Internet Explorer 8 (IE8) across all our platforms (ASP.NET, XAF, DevExtreme, etc.).

    Microsoft Ends Support for IE8

    Back in August 2014, Microsoft announced its plan to end support for older browsers:

    After January 12, 2016, only the most recent version of Internet Explorer available for a supported operating system will receive technical support and security updates. For example, customers using Internet Explorer 8, Internet Explorer 9, or Internet Explorer 10 on Windows 7 SP1 should migrate to Internet Explorer 11 to continue receiving security updates and technical support. For more details regarding support timelines on Windows and Windows Embedded, see the Microsoft Support Lifecycle site. - ieblog

    Therefore, since January 2016, IE8 is no longer receiving any updates, including security updates. I’ve don't need to tell you how dangerous this is for your users. Because of these very real concerns, we’ve made the decision to remove explicit support for IE8 and we strongly encourage you to do the same, if you have not already done so.


    Are you still supporting IE8? If you still have to for the indefinite future, you can use the v15.2 release, but my advice is to upgrade to the most recent and supported version of Internet Explorer.

    Be aware that we are also discussing removing support for IE9 and IE10 in a future version. (For example, IE9 is only supported on Vista SP1 and support for that is being wound down.) Our advice is to migrate to IE11 as soon as is practicable.

    Feedback

    I would love to hear your feedback on this decision. How will this affect you?

    Leave me a comment below or email me directly: mharry@devexpress.com

    Thanks!

  • ASP.NET AJAX Control Toolkit - New Release v16.1 and GitHub Hosted!

    A new release of the ASP.NET AJAX Control Toolkit, v16.1, is now available. We've included new features and several bug fixes.

    One Year Anniversary

    Today marks the one year anniversary since DevExpress released the first version of the updated ASP.NET AJAX Control Toolkit:

    March 2015 - Announcing the ASP.NET AJAX Control Toolkit - v15.1

    And it has been one and half years since we took over maintenance (and care) of the ASP.NET AJAX Control Toolkit:

    September 2014 - LONG LIVE The Ajax Control Toolkit - Open Source and now maintained by DevExpress

    As we continue to fix and improve the ASP.NET AJAX Control Toolkit, we would like to encourage more developer interaction with this open-source library. So it's time to make a major move to help the library:

    Hello Github, Goodbye CodePlex

    The ASP.NET AJAX Control Toolkit respository has now officially moved from CodePlex to Github.

    DevExpress ASP.NET AJAX Control Toolkit GitHub

    https://github.com/DevExpress/AjaxControlToolkit/

    We chose Github because it is a great community of open-source developers and projects. And because the ASP.NET AJAX Control Toolkit is an open-source project, we would love to have more developers get involved and submit their code.

    If you have never used GitHub then take a look at their free great getting started guide: GitHub Bootcamp

    Documentation

    The documentation has been ported and is now hosted on GitHub as well:

    ASP.NET AJAX Control Toolkit Documentation

    Issues

    The CodePlex page will now be mostly deactivated with redirect links to GitHub. If you need to report an issue, please use GitHub:
