Raised when the user clicks the logout button.
Assembly: System.Web (in System.Web.dll)
The event is raised on the server when the user clicks the logout link. The logout process does not occur until after this event, and user information is still available.
The event allows you to cancel the logout process if the user must complete an activity before leaving the Web site, such as purchasing items in a shopping cart or submitting changes to a database. You can cancel the event by setting the Cancel property of the LoginCancelEventArgs parameter to true.
Use the event to provide additional processing, such as clearing per-user data, before a user logs out of a site.
