Hi

I use this code for submit my form to our bank gateway:

<%@ Page Language="C#" %>

<!DOCTYPE html>

<script runat="server">

    protected void submit(object sender, EventArgs e)

    {

        ClientScript.RegisterStartupScript(typeof(Page),

            "ClientScript",

            "<script language='javascript' type='text/javascript'> postRefId();</"+"script> ",

            false);

    }

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title>test</title>

    <script language="javascript" type="text/javascript">

        function postRefId() {

            var form = document.createElement("form");

            form.setAttribute("method", "POST");

            form.setAttribute("action", "http://bmi.ir");

            form.setAttribute("target", "_self");

            document.body.appendChild(form);

            form.submit();

            document.body.removeChild(form);

        }

    </script>

</head>

<body>

    <form id="form1" runat="server">

        <div>

             <asp:Button ID="Button1" runat="server"

             Text="Button"

             OnClick="submit" />

        </div>

    </form>

</body>

</html>

But when I use RadAjaxPanel like this, I can’t submit my form:

<%@ Page Language="C#" %>

<!DOCTYPE html>

<script runat="server">

    protected void submit(object sender, EventArgs e)

    {

        ClientScript.RegisterStartupScript(typeof(Page),

            "ClientScript",

            "<script language='javascript' type='text/javascript'> postRefId();</"+"script> ",

            false);

    }

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title>test</title>

    <script language="javascript" type="text/javascript">

        function postRefId() {

            var form = document.createElement("form");

            form.setAttribute("method", "POST");

            form.setAttribute("action", "http://bmi.ir");

            form.setAttribute("target", "_self");

            document.body.appendChild(form);

            form.submit();

            document.body.removeChild(form);

        }

    </script>

</head>

<body>

    <form id="form1" runat="server">

        <div>

            <tlk:RadScriptManager ID="RadScriptManager1" runat="server" />

            <tlk:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

                    <asp:Button ID="Button1" runat="server"

                    Text="Button"

                    OnClick="submit" />

            </tlk:RadAjaxPanel>

        </div>

    </form>

</body>

</html>

How can I fix it?

= "ddlName_SelectedIndexChanged"

Anyone knows how to only let the value of the second Combo box refresh, not the whole page? Any help is very much appreciated.
