Hi Teera,
 
You don't need to add "Sys.Application.add_load...". Your method should look like this one:

RadAjaxManager1.ResponseScripts.Add(@"radalert('RadWindow <b>Prometheus</b>!', 330, 210);")

More about calling radalert from codebehind is available in the following KB article:
http://www.telerik.com/support/kb/aspnet-ajax/window/calling-radalert-from-codebehind.aspx

Let us know if you have any other questions.


Sincerely yours,

Hello Teera,

The error means that radalert method doesn't exist on the page. In case that you didn't add a  RadWindowManager to your page - please add it.
Here it is a simple example, which illustrates how to show radalert after Ajax call:
ASPX:
<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<head id="Head1" runat="server">
</head>
<body class="BODY">
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="Button1" >
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="Button1"/>
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server"></telerik:RadWindowManager>
    <div>
        <asp:Button ID="Button1" runat="server" Text="showAlert" OnClick="Button1_Click"/>
    </div>
    </form>
</body>
</html>
Codebehind:
protected void Button1_Click(object sender, EventArgs e)
   {
       RadAjaxManager1.ResponseScripts.Add("radalert('Welcome to RadWindow <b>Prometheus</b>!', 330, 210);");
   }
In case that you still experience this JavaSciprt error, please open a new support thread and send us a running project, which will help us to reproduce the error locally. Once we receive it, we will do our best to help you.
