    We are upgrading our code from .Net 3.5 to 4.0 and an issue has come up. The way we previously did login is now having an error on the Response.Redirect. From what have found doing research, it seems to be an error that has something to do with Ajax, adding to the response, and redirect.  Unfortunately I can not find a solution to this problem.

    The error we get is "Uncaught Sys.WebForms.PageRequestManagerParserErrorException" via the javascript from Telerik.Web.UI.WebResource.axd.

    The code snippets we have below work under .Net 3.5 but do not work after attempting the 4.0 upgrade. The authentication cookies do get added as I can manually type the url that we are supposed to redirect to. However, the automatic redirect does not work. 

    <%@ Page Language="C#" MasterPageFile="~/masterpages/WebMain.master" AutoEventWireup="true" Inherits="Default" Codebehind="Default.aspx.cs"%>
    <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
    <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolderMaster" Runat="Server">
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                    <telerik:AjaxSetting AjaxControlID="Login">
                            <telerik:AjaxUpdatedControl ControlID="Login" LoadingPanelID="AjaxLoadingPanel1" />
        <telerik:RadAjaxLoadingPanel ID="AjaxLoadingPanel1" runat="server" />   
        <div id="divLogin" runat="server">
            <table align="center">
                    <td align="center">
                        <asp:Login ID="Login" runat="server"
                            OnAuthenticate="Login_Authenticate" DisplayRememberMe="False"
                            Orientation="Horizontal" TextLayout="TextOnTop" TitleText="" LoginButtonStyle-Height="25px" LoginButtonStyle-Width="50px">
    protected void Login_Authenticate(object sender, AuthenticateEventArgs e)
         Response.Redirect(pageUrl, false);

    The solution I found was that this issue only appears when debugging so it was not a real issue. The double call only happens when a break point is placed that gets hit allowing the javascript to complete before the code behind.

    So while debugging it appears to be an issue but when not debugging the issue does not appear.

    I'm tired so I posted the solution I had to another issue sorry. The solution was to use RadAjaxManager.Redirect() instead of the Response.Redirect(). Ignore my last post.
