A control container that supports the popup functionality.
public class PopupControlContainer : BarPopupExpandable
Public Class PopupControlContainer Inherits BarPopupExpandable
A PopupControlContainer object can contain other controls, and it can be displayed as a dropdown window. For example, you can associate a PopupControlContainer object with a BarSplitButtonItem object. Another use case is to replace a context menu with a PopupControlContainer object. To specify a context menu (or a popup control that will be used as a context menu) for a UIElement, use the BarManager.DXContextMenu property.
The PopupControlContainer's content is specified by the PopupControlContainer.Content property.
If you are observing an exception at design time when you initialize a property with a PopupControlContainer object, try initializing this property with the PopupControlContainerInfo object instead. The PopupControlContainerInfo creates a corresponding PopupControlContainer internally and has the same settings as the PopupControlContainer.
