Occurs before the view is changed.
Assembly: System.Web (in System.Web.dll)
When the LoginView control switches views, it removes the controls from the previous template and creates new child controls from the new template. The event is raised before the previous controls are removed.
Use the event to perform any processing, such as saving control information, necessary before the controls are removed.
The event is only raised if the login status for a user changes during a postback to the page. The event will not be raised if a user logs in using the Login control, or if the user logs out using the LoginStatus control. The event will also not occur if a user is logged in or out followed by a redirect. An example of when the event will occur is when a user is logged out by calling the SignOut method without being redirected to another page. During the next postback to the page, the LoginView control will detect the change in the login status for the user, and then raise the event.
