Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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