.NET Framework Class Library
Login..::.LoggedIn Event

Occurs when the user logs in to the Web site and has been authenticated.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)
Syntax

Visual Basic (Declaration)
Public Event LoggedIn As EventHandler
Visual Basic (Usage)
Dim instance As Login
Dim handler As EventHandler

AddHandler instance.LoggedIn, handler
C#
public event EventHandler LoggedIn
Visual C++
public:
 event EventHandler^ LoggedIn {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}
JScript
JScript does not support events.
ASP.NET
<asp:Login OnLoggedIn="EventHandler" />
Remarks

The LoggedIn 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 LoggedIn event to provide additional processing, such as accessing per-user data, after the user is authenticated.

When a user submits his or her login information, the Login control first raises the LoggingIn event, then the Authenticate event, and finally the LoggedIn event.

NoteNote:

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 LoggedIn event that rely on the view state.

For more information about handling events, see Handling and Raising Events.

Examples

The following code example uses the LoggedIn event to call a site-specific method that keeps a record of user logins.
