e: DataGridViewCellPaintingEventArgs

A DataGridViewCellPaintingEventArgs that contains the event data.

Remarks

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

The OnCellPainting 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 OnCellPainting(DataGridViewCellPaintingEventArgs) in a derived class, be sure to call the base class's OnCellPainting(DataGridViewCellPaintingEventArgs) method so that registered delegates receive the event.
