A GridViewCancelEditEventArgs that contains event data.
Exceptions
There is no handler for the RowCancelingEdit event.
Remarks
The RowCancelingEdit event is raised when the Cancel button of a row in edit mode is clicked, but before the row exits edit mode. This enables you to provide an event-handling method that performs a custom routine, such as stopping the cancel operation if it would put the row in an undesired state, whenever this event occurs.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnRowCancelingEdit 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 OnRowCancelingEdit(GridViewCancelEditEventArgs) in a derived class, be sure to call the base class's OnRowCancelingEdit(GridViewCancelEditEventArgs) method so that registered delegates receive the event.
