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.

No code example is currently available or this language may not be supported.
<Popup Name="myPopupIsOpen" IsOpen="True" 
       HorizontalOffset=".5cm" VerticalOffset="1cm">
  <TextBlock Background="Yellow">Popup Text</TextBlock>
</Popup>
