  1. I use Ajax asp:UpdatePanel in my site, it work beautiful in the local host, but when i deploy my site to Winhost i get the following error message:

    Parser Error Message: Unknown server tag 'asp:ScriptManager'.

    Source Error:

    Line 10: <form id="form1" runat="server">
    Line 11: <div>
    Line 12: <asp:ScriptManager ID="ScriptManager1" runat="server">
    Line 13: </asp:ScriptManager>
    Line 14: <asp:UpdatePanel ID="UpdatePanel1" runat="server">

    Source File: /inbox.aspx Line: 12

    I'm wondring if the Winhost server support Ajax?

    Yes I can assure you that AJAX is installed and supported on our hosting environment. What version of AJAX are you trying to use. The servers GAC only have AJAX version 3.5 installed. If you want another version, you will need to make sure you upload it to the applications bin directory and call on the assemblies from there.
  3. The problem solved by using the right version of Ajax
  4. Thanks for posting the follow-up.
