UIElement.OnIsKeyboardFocusedChanged Method

Invoked when an unhandled IsKeyboardFocusedChanged event is raised on this element. Implement this method to add class handling for this event.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

'Declaration
Protected Overridable Sub OnIsKeyboardFocusedChanged ( _
	e As DependencyPropertyChangedEventArgs _
)

This virtual method is raised when the value of the IsKeyboardFocused dependency property changes. The virtual method is raised 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.
