HttpException

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

The OnItemInserting method is called by the FormView control to raise the ItemInserting 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 OnItemInserting 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 OnItemInserting in a derived class, be sure to call the base class's OnItemInserting method so that registered delegates receive the event.
