Parameters

e: GridViewDeleteEventArgs

A GridViewDeleteEventArgs that contains event data.

Exceptions

HttpException

There is no handler for the RowDeleting event.

Remarks

The RowDeleting event is raised when a row's Delete button is clicked, but before the GridView control deletes the row. This enables you to provide an event-handling method that performs a custom routine, such as canceling the delete operation, whenever this event occurs.

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

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