RadialContextMenu Class

The menu where items are arranged in a circle.

Namespace: DevExpress.Xpf.Bars

Assembly: DevExpress.Xpf.Core.v23.2.dll

NuGet Package: DevExpress.Wpf.Core


public class RadialContextMenu :


A Radial Menu is a Microsoft Note 2013 inspired pop-up menu, in which items are arranged in a circle.


In XAML, radial menu items (BarItem and BarItemLink descendants) can be created by defining them between the RadialContextMenu start and end tags. To define a sub-menu item (a menu whose items are displayed at a nested level), use the BarSplitButtonItem object.

You can assign a Radial Menu to a control using the BarManager.DXContextMenu attached property.


This example shows how to assign a RadialContextMenu to a text box and initialize the menu with items.

To assign the RadialContextMenu to the text box, the BarManager.DXContextMenu attached property is used.

The radial menu displays three regular buttons (Copy, Cut and Paste) and one sub-menu (Select All) that provides access to two additional items (Clear and Select All). Commands are assigned to the buttons with the Command properties.


The radial menu’s DataContext is bound to the window’s DataContext. This DataContext is set to a RadialContextMenuViewModel class descendant, which is automatically generated by the DevExpress.Mvvm.POCO.ViewModelSource object. This descendant automatically generates commands for all public methods in the RadialContextMenuViewModel class (the ClearSelectionCommand is generated for the ClearSelection method).
