Remarks

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

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(DataGridViewCellErrorTextNeededEventArgs) in a derived class, be sure to call the base class' OnCellErrorTextNeeded(DataGridViewCellErrorTextNeededEventArgs) method so that registered delegates receive the event.
