Parameters

e: GridViewUpdateEventArgs

A GridViewUpdateEventArgs that contains event data.

Exceptions

HttpException

There is no handler for the RowUpdating event.

Remarks

The RowUpdating event is raised when a row's Update button is clicked, but before the GridView control updates the row. This enables 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 Handling and Raising Events.

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