Remarks

The OnAnswerLookupError method is called when the user's answer to the password recovery confirmation question does not match the answer stored in the Web site data store. The default implementation raises the AnswerLookupError event.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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