For more information about handling events, see Handling and Raising Events.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnCurrentChanged 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.
