Remarks
Because this event uses bubbling routing, the element that lost focus might be a child element instead of the element where the event handler is actually attached. Check the Source in the event data to determine the actual element that lost focus.
This event creates an alias for the Keyboard.LostKeyboardFocus attached event for this class, so that LostKeyboardFocus is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the LostKeyboardFocus event are attached to the underlying Keyboard.LostKeyboardFocus attached event and receive the same event data instance.
