[BindableAttribute(true)]
public bool StaysOpen { get; set; }
<object StaysOpen="bool" .../>

Property Value

Type: System.Boolean
true if the Popup control closes when IsOpen property is set to false; false if the Popup control closes when a mouse or keyboard event occurs outside the Popup control. The default is true.

Identifier field

StaysOpenProperty

Metadata properties set to true

None

When the StaysOpen property is set to true, Popup stays open until it is explicitly closed by setting the IsOpen property to false. When StaysOpen is false, the Popup control intercepts all mouse and keyboard events to determine when one of these events occurs outside the Popup control.

The following example shows how to set the StaysOpen property.

myTextBlockPopup.StaysOpen = true;
<DockPanel  Width="500" Background="Aqua">
  <Popup Placement="Center" PlacementRectangle="0,0,30,50"  
          IsOpen ="True" StaysOpen="True"
          PopupAnimation="Fade">
    <TextBlock Background="Purple">Popup Text</TextBlock>
  </Popup>
</DockPanel>
