Public Custom Event TakeFocusRequested As TypedEventHandler(Of DesktopWindowXamlSource, DesktopWindowXamlSourceTakeFocusRequestedEventArgs) 

Event Type

TypedEventHandler<DesktopWindowXamlSource,DesktopWindowXamlSourceTakeFocusRequestedEventArgs>

Remarks

When you add a DesktopWindowXamlSource to your desktop application, by default the DesktopWindowXamlSource does not automatically handle focus navigation via keyboard events such as the Tab or arrow keys. Handle this event to programmatically give focus to the next focusable element in the host application when the user navigates away from the DesktopWindowXamlSource.
