The LoginView Control

The LoginView control is a Web Server control, which is used to display two different views of a Web page of any website, depending on whether the user has logged on to a Web page as a registered user or a visitor. The LoginView control provides a way of altering the look of the page or showing different content to different groups of users. This control has the built-in functionality to gether the current user's status and roles. If the user is authenticated, the control displays the appropriate information to the user with the help of its three view templates which are:
  • AnonymousTemplate : Displayed when the user is not logged in
  • LoggedInTemplate : Displayed when the user is logged in 
  • RoleGroups : Displayed when the user who has logged in, is a member of a specific role with defined role group templates
