GridView.OnRowCancelingEdit Method

Raises the RowCancelingEdit event.

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

abstract OnRowCancelingEdit : 
        e:GridViewCancelEditEventArgs -> unit 
override OnRowCancelingEdit : 
        e:GridViewCancelEditEventArgs -> unit 

ExceptionCondition
HttpException

There is no handler for the RowCancelingEdit event.

The RowCancelingEdit event is raised when the Cancel button of a row in edit mode is clicked, but before the row exits edit mode. This enables you to provide an event-handling method that performs a custom routine, such as stopping the cancel operation if it would put the row in an undesired state, whenever this event occurs.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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