Metadata properties set to true
A Popup control can only contain transparent content when the application runs with full trust. An application that runs with full trust has complete access to system resources and is typically installed on the local system. For more information, seeSecurity (WPF).
This property cannot be set to true when the Popup is hosted in a XAML browser application (XBAP).
If the property is set to true in an application that does not run in full trust, the property value is changed to false. An application that is hosted in a browser is an example of an application that does not run in full trust.
The following example shows how to set the property on a Popup control.
