BarSplitButtonItem Class

Represents a bar button item supporting the drop-down functionality.

Namespace: DevExpress.Xpf.Bars

Assembly: DevExpress.Xpf.Core.v24.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

public class BarSplitButtonItem :
    BarButtonItem

Remarks

The BarSplitButtonItem supports the drop-down functionality, displaying a drop-down window when clicking the item link. The BarSplitButtonItem contains the main button, displaying the item’s content and glyph, and a Down Arrow button. Clicking the main button invokes the ItemClick events (BarItem.ItemClick and BarManager.ItemClick) and a command (BarItem.Command). Clicking the Down Arrow button invokes the drop-down control, specified by the BarSplitButtonItem.PopupControl property.

BarSplitButtonItem

You can hide the Down Arrow button via the BarSplitButtonItem.ActAsDropDown property. In this instance, clicking the main button invokes the ItemClick events and the specified command. And in addition, the assigned drop-down control pops up.

BarSplitButtonItem can be used to implement a sub-menu in a RadialContextMenu.

Example

This example creates a BarSplitButtonItem (a button with drop-down). Click the button’s down arrow to display a popup window. To add a custom popup content, use the PopupControlContainer as the PopupControl.

The following image shows the result:
