Assembly: System.Web (in system.web.dll)
A GridViewUpdateEventArgs that contains event data.
The RowUpdating event is raised when a row's Update button is clicked, but before the GridView control updates the row. This allows you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnRowUpdating 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 OnRowUpdating in a derived class, be sure to call the base class's OnRowUpdating method so that registered delegates receive the event.
