I have a standard Login form
<asp:Login ID="lgnExcel" DestinationPageUrl="login/data.aspx" OnAuthenticate="Login1_Authenticate" runat="server">
Is it possible to attach the Username as a query string with the DestinationPageUrl or reference the value in the code behind. I've tried lgnExcel.UserName.ToString() but coudldn't get to show any help would be great. Thanks.
