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.

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">

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

<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.
