Ajax "AsyncPostBackError" for ScriptManager, JScript error problem in .NetFramework 3.5 SP1

manpakhong — Sat, 20 Jun 2009 02:33:08 GMT

Dear all,

I migrated my company web applications from Visual Studio 2005, .NetFramework 2.0, ASP.net, Ajax extensions 1.0 to Visual Studio 2008 SP1, .NetFramework 3.5 SP1.

I find that the code that contained AsyncPostBackError, when it is triggered. It will have JScript error.

======HTML Parts=====================================

I simplified the code as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>

<!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></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        <asp:ScriptManager ID="ScriptManager1" runat="server"
            onasyncpostbackerror="ScriptManager1_AsyncPostBackError">
        </asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
            </ContentTemplate>
        </asp:UpdatePanel>

    </div>
    </form>
</body>
</html>

===============Code Behind C# part =============================

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        throw new ArgumentException();
    }
    protected void ScriptManager1_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e)
    {
        this.ScriptManager1.AsyncPostBackErrorMessage =
            e.Exception.Message;
    }
}

An error is appeared:
Microsoft Visual Studio: Microsoft JScript runtime error:
Sys.WebForms.PageRequestManagerServerErrorException: Value does not fall within the excepted range.
=========================================================================================================

And It can be fixed by the following solution:
