Gets or sets a value that indicates whether the Popup is visible.
(in PresentationFramework.dll)XMLNS for XAML:
Public Property IsOpen As Boolean
<object IsOpen="bool" .../>
Type: System.Booleantrue 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.
The following example shows how to set the IsOpen property.
myPopupIsOpen.IsOpen = True
<Popup Name="myPopupIsOpen" IsOpen="True"
<TextBlock Background="Yellow">Popup Text</TextBlock>
