LoginStatus.OnLoggingOut Method

Note: This method is new in the .NET Framework version 2.0.

Raises the LoggingOut event when a user clicks the logout link on the LoginStatus control.

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

protected virtual void OnLoggingOut (
	LoginCancelEventArgs e
)
protected void OnLoggingOut (
	LoginCancelEventArgs e
)
protected function OnLoggingOut (
	e : LoginCancelEventArgs
)

Parameters

e

A LoginCancelEventArgs that contains event data.

Use the LoggingOut event to provide additional processing, such as cleaning up per-user data, before a user logs out of a site. The OnLoggingOut event can be canceled, so you can give the user the option of saving data such as a shopping cart or database changes before leaving the Web site.

For more information about handling events, see Events and Delegates.

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

The following code example attaches an event handler to the OnLoggingOut event. The event handler updates a field on the form, and then cancels the logout attempt.

    void LoginStatus1_LoggingOut(Object sender, System.Web.UI.WebControls.LoginCancelEventArgs e)
    {
        Message.Text = "LoggingOut event. Don't go away now.";
        e.Cancel = true;
    }
