protected function OnCellErrorTextNeeded ( e : DataGridViewCellErrorTextNeededEventArgs )

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnCellErrorTextNeeded 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 OnCellErrorTextNeeded in a derived class, be sure to call the base class’s OnCellErrorTextNeeded method so that registered delegates receive the event.
