Raises the ItemDeleting event.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The ItemDeleting event is raised when an item's Delete button is clicked or the DeleteItem method is called, but before the ListView control deletes the item. (A Delete button is a button control whose CommandName property is set to "Delete".) This enables you to perform a custom routine whenever this event occurs, such as canceling the delete operation.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The method also enables 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 you override in a derived class, call the base class's method so that registered delegates receive the event.
