Examples

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

<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
void SiteSpecificUserLoggingMethod(string UserName)
{
    // Insert code to record the current date and time
    // when this user was authenticated at the site.
}

void OnLoggedIn(object sender, EventArgs e)
{
    SiteSpecificUserLoggingMethod(Login1.UserName);
}
</script>

        </form>
    </body>
</html>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
Sub SiteSpecificUserLoggingMethod(ByVal UserName As String)
    ' Insert code to record the current date and time
    ' when this user was authenticated at the site.
End Sub

Sub OnLoggedIn(ByVal sender As Object, ByVal e As EventArgs)
    SiteSpecificUserLoggingMethod(Login1.UserName)
End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
    <title>ASP.NET Example</title>
</head>
<body>
        <form id="form1" runat="server">
            <asp:Login id="Login1" runat="server" OnLoggedIn="OnLoggedIn"></asp:Login>

        </form>
    </body>
</html>

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 their login information, the Login control first raises the LoggingIn event, then the Authenticate event, and finally the LoggedIn event.

Note

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.
