ListView.OnItemDeleting Method (ListViewDeleteEventArgs)
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 NIB: Raising an Event.
Themethod 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 overridein a derived class, call the base class's method so that registered delegates receive the event.
