Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
The OnRowStateChanged 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 Inheritors:
When overriding OnRowStateChanged in a derived class, be sure to call the base class's OnRowStateChanged method so that registered delegates receive the event.
