For more information about how to handle events, see Handling and Raising Events.
The OnInit 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.
When overriding the OnInit(EventArgs) method in a derived class, be sure to call the OnInit(EventArgs) method for the base class so that registered delegates receive the event.
