Introduction
The LoginStatus control has two states, logged in to the Web site and logged out of the Web site, determined by the IsAuthenticated property of the Page object's Request property.
The LoginStatus control displays either a text or an image link, depending on the setting of the LoginImageUrl and LogoutImageUrl properties. You can display either text or images for one or both states.
Note
If you are not familiar with the set of login controls available in ASP.NET, see ASP.NET Login Controls Overview before continuing. For a list of other topics related to login controls and membership, see Managing Users by Using Membership.
When a user is not logged in to the site, the LoginStatus control provides a link to the login page defined in the application configuration settings. When the user is logged in to the Web site, the LoginStatus control provides a link to log out of the Web site. Logging out of the Web site clears the user's authentication status and when using cookies will clear the cookie from the user's client computer. On any subsequent visit to the Web site, the LoginStatus control will display the prompt to log in.
The logout behavior is controlled by the LogoutAction property, which specifies whether to refresh the current page, redirect the user to the login page defined in the application configuration settings, or redirect the user to a page specified by the LogoutPageUrl property. The default is to refresh the current page.
Note
When a user uses the LoginStatus control to log out of a Web site, all data present in view state and all post data is lost.
