public ref class LoginCancelEventArgs : public EventArgs

A cancelable event is raised when a component is about to perform an action that can be canceled, such as logging on to a Web site.

The LoginCancelEventArgs class provides the Cancel property to indicate whether the event should be canceled. A LoginCancelEventArgs object is used with controls that have cancelable actions, such as the Login control, the CreateUserWizard control, and the PasswordRecovery control.

The following code example uses the LoggingIn event to ensure that the user has entered a well-formed e-mail address in the UserName property. If not, the LoggingIn event handler cancels the logon attempt by setting the Cancel property of the LoginCancelEventArgs object to true.Then the error message specified in the InstructionText property is displayed.
