Parameters

e: GridViewEditEventArgs

A GridViewEditEventArgs that contains event data.

Exceptions

HttpException

There is no handler for the RowEditing event.

Remarks

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

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

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