Assembly:  PresentationFramework (in PresentationFramework.dll)

[BindableAttribute(true)]
public bool IsOpen { get; set; }

Property Value

Type: System.Boolean

true if the Popup is visible; otherwise, false. The default is false.

If a control uses a Popup as part of its default style, bind the IsOpen property of the Popup to a property of the control. For example, a ComboBox can bind its IsDropDownOpen property to the IsOpen property of the Popup. This simplifies the logic for controlling when the Popup is visible.
