Invoked when an unhandled IsKeyboardFocusedChanged event is raised on this element. Implement this method to add class handling for this event.
Assembly: PresentationCore (in PresentationCore.dll)
This virtual method is called when the value of the IsKeyboardFocused dependency property changes. The virtual method is called first and can manipulate the event data as necessary. Then the IsKeyboardFocusedChanged event is raised with that same event data instance. Notice that the IsKeyboardFocusedChanged event is not a routed event. Therefore, you cannot mark it as handled in the class handler.
This method has no default implementation. Because an intermediate class in the inheritance might implement this method, we recommend that you call the base implementation in your implementation. You may call base either before or after your special handling, depending on your requirements.
is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
