Hi,

I am experiencing a very odd issue. If you have a RadAsyncUpload in an UpdatePanel on Windows XP you get the following js error:

'Error: uncaught exception: Syntax error, unrecognized expression: [object Object]'

This error appears to be related to JQuery. I get the error in any browser on Windows XP but on no browser on Windows Vista. The following code will reproduce the error:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<head runat="server">

<title>RadAsyncUpload in UpdatePanel on Windows XP Test</title>

</head>

<body>

<form runat="server" enctype="multipart/form-data">

<asp:ScriptManager runat="server" />

<asp:UpdatePanel ID="UpdatePanel" runat="server"><ContentTemplate>

<rad:RadAsyncUpload runat="server" MultipleFileSelection="Automatic" />

<asp:Button runat="server" OnClick="OnClick" Text="Run Test" />

</ContentTemplate></asp:UpdatePanel>

</form>

</body>

</html>

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page

{

protected void OnClick(object sender, EventArgs e)

{

System.Web.UI.ScriptManager.RegisterStartupScript(UpdatePanel, typeof(string), Guid.NewGuid().ToString(), "alert('Successful');", true);

}

Or you can test at http://xptest.abcweblink.com/

Notice that the mere presence of the RadAsyncUpload causes the error even though it doesn't actually do anything.

Thank you for any assistance.
