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.
