Remarks

The OnVerifyingUser method is called after the user submits a user name on the initial screen and before the user name is validated by the membership provider. The default implementation raises the VerifyingUser event.

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

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