Gets or sets a value that indicates whether the Popup is visible.
Assembly: PresentationFramework (in PresentationFramework.dll)
If a control uses a Popup as part of its default style, bind the property of the Popup to a property of the control. For example, a ComboBox can bind its IsDropDownOpen property to the property of the Popup. This simplifies the logic for controlling when the Popup is visible.
