Attributes

BindableAttribute

Examples

The following example shows how to set the IsOpen property.

myPopupIsOpen.IsOpen = true;

myPopupIsOpen.IsOpen = True

<Popup Name="myPopupIsOpen" IsOpen="True" 
       HorizontalOffset=".5cm" VerticalOffset="1cm">
  <TextBlock Background="Yellow">Popup Text</TextBlock>
</Popup>

Remarks

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.
