Occurs when the user logs in to the Web site and has been authenticated.
Assembly: System.Web (in System.Web.dll)
The event is raised after the authentication provider checks the user's credentials and the authentication cookie is queued to send to the browser in the next response. Use the event to provide additional processing, such as accessing per-user data, after the user is authenticated.
When a user uses the Login control to log in to a Web site, all data in the view state and all post data is lost. Do not perform actions in the event that rely on the view state.
