The OnDropDownOpened 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 OnDropDownOpened in a derived class, make sure to call the base class’s OnDropDownOpened method so that registered delegates receive the event.
