System.Web 2.0.0.0 System.ComponentModel.CancelEventArgs

The class is used in the method to provide access to the business object instance after any data operations that are using the control and business object are performed, but before the business object is destroyed. The business object is accessed using the property. By adding a delegate to handle the event, you can access any publicly exposed members of the business object to perform any final work or clean up.

The method is not called by the control, if the method that performs data operations is a static method. No business object instance is created when the method is static.

The control exposes many events that you can handle to work with the underlying business object at various times in its lifecycle. The following table lists the events and the associated classes and event handler delegates.
