Login::LoggingIn Event

Occurs when a user submits login information, before authentication takes place.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
 event LoginCancelEventHandler^ LoggingIn {
	void add (LoginCancelEventHandler^ value);
	void remove (LoginCancelEventHandler^ value);
}
<asp:Login OnLoggingIn="LoginCancelEventHandler" />

The LoggingIn event is raised when a user submits login information but before the user is authenticated on the Web site. Use the LoggingIn event to set up any information that you need before authenticating a user.

You can cancel a login attempt during the LoggingIn event by setting the Cancel property of the CancelEventArgs object to true.

After the LoggingIn event is raised, the Login control raises the Authenticate event and then the LoggedIn event.

For more information about handling events, see Handling and Raising Events.

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 cancels the login attempt and displays an error message using the InstructionText property.

No code example is currently available or this language may not be supported.
