This method is called when the FormView control is not bound to a data source control, the user did not cancel the update operation, and an event handler is not registered for the event.

The OnItemUpdating method is called by the FormView control to raise the ItemUpdating event. It is generally used by control developers when extending the FormView class.

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

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