What's New in 2021 Volume 1: WPF

What’s New in 2021 Volume 1: WPF

In the Essential Studio 2021 Volume 1 release, Syncfusion has exciting new controls and updates in almost all its supported platforms. In this blog, we are going to look at the updates to the WPF controls in this 2021 Volume 1 release.

.NET 5.0 toolbox support

Previously in .NET 5.0 projects, Syncfusion WPF controls would be listed in the Visual Studio toolbox only when their corresponding NuGet packages were installed in the project. Now, the WPF UI controls are added to the toolbox via an installer.

Preview to production-ready controls

The following WPF controls have been developed to meet industry standards and are now marked as production-ready in the 2021 Volume 1 release:

Fluent light and dark themes

With this release, new Fluent light and dark themes are provided for both native framework and Syncfusion controls. The Fluent themes include design improvements like reveal highlight, reveal focus (high visibility keyboard visual feedback), and the option to enable touch design. You can customize Fluent themes using WPF Theme Studio or WPF Skin Manager just as you would other themes.

For more details, refer to our Fluent theme documentation.

High visibility keyboard visual feedback (reveal focus)

Reveal focus, or high visibility keyboard visual feedback, is an effect that shows a border on focusable elements when the user moves keyboard focus to that element. Now, you can enable or disable reveal focus for both framework and Syncfusion WPF controls using the WPF Skin Manager. The reveal focus is enabled by default in the Fluent theme, and you can enable it for other themes by setting the FocusVisualKind property of the theme.

For more information, refer to our WPF reveal focus documentation.

Windows 10-like compact scroll viewer

In Windows 10, the scroll bar in the scroll viewer is visualized using a panning indicator and traditional scroll bar, based on user interaction. Now, the Skin Manager has a ScrollBarMode property to enable a Windows 10-like compact scroll bar in all themes. By default, the compact scroll viewer is enabled in the Fluent themes, and you can enable this design in the other themes by using the ScrollBarMode property.

Size mode: touch UI for themes

With this  2021 Volume 1 release, all 13 themes in WPF Theme Studio support size mode. Using this, you can enable touch mode alignment by setting the SizeMode property of the Skin Manager.

For more information, refer to our WPF touch UI documentation.

Spin button support in all numeric input controls

Our WPF Integer TextBox, Double TextBox, Percent TextBox, and Currency TextBox controls provide a built-in spin button which can be enabled by setting the ShowSpinButton property. Now, you can use the spin button to increase and decrease numeric values in the editor.

Keyboard navigation

Our WPF Navigation Drawer now provides complete keyboard support to navigate between menu items using the Tab and arrow keys. This feature is also applicable in the sidebar menu.


MVVM support to map node expand states

Our WPF TreeView now provides support to save and retrieve node expansion states of a property in the underlying mode object. Even dynamic changes can be tracked.

Cancel editing

With this release, end users can cancel editing by pressing the Esc key, which reverses the edited value and returns it to its original value by using IEditableObject implementation in the model class.

With this 2021 Volume 1 release, the Text Input Layout control allows loading WPF framework and Syncfusion combo box and autocomplete input controls, such as ComboBoxAdv, and SfTextBoxExt, in it.

For more information, refer to our supported input views documentation.

UI virtualization

The WPF Property Grid control now loads data faster using built-in UI virtualization. You can enable or disable this feature using the IsVirtualizing property.


Diagram ribbon enhancement

The ribbon of our WPF Diagram control now includes commands to apply different appearances to diagrams with themes and variants from the Design tab. A theme in the Diagram control is a set of colors and effects that can be applied to a drawing with a single click.

Visual Studio extensions

The Syncfusion WPF windows provide an option to quickly customize the window title bar. They also come with various built-in themes to provide an appealing user interface.
