ListView::OnItemEditing Method (ListViewEditEventArgs^)
Raises the ItemEditing event.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The ItemEditing event is raised when an item's Edit button is clicked, but before the ListView control enters edit mode. (An Edit button is a button control whose CommandName property is set to "Edit".) This enables you to perform a custom routine whenever this event occurs, such as canceling the edit 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.
