GridView.OnRowUpdating Method (GridViewUpdateEventArgs)


Raises the RowUpdating event.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

abstract OnRowUpdating : 
        e:GridViewUpdateEventArgs -> unit
override OnRowUpdating : 
        e:GridViewUpdateEventArgs -> unit

Exception Condition

There is no handler for the RowUpdating event.

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 NIB: 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.
