Do not rely on this method to determine when the control loses focus.
The OnLostFocus method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to InheritorsWhen overriding OnLostFocus in a derived class, be sure to call the base class’s OnLostFocus method so that registered delegates receive the event.
