Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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