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).
