Parameters

e: DataGridViewCellValidatingEventArgs

A DataGridViewCellValidatingEventArgs that contains the event data.

The value of the ColumnIndex property of e is greater than the number of columns in the control minus one.

-or-

The value of the RowIndex property of e is greater than the number of rows in the control minus one.

Remarks

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

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