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:

Is it the bug of .NetFramework 3.5 SP1? or otherthing else?
