Hello,

Quick question and I would really appreciate if anybody could helps me.
Here are the steps to reproduce the problem. Create simple ASP.Net
application. In code behind added protected class variable:

protected string _result = "No result";

Page Load event has:

if (IsPostBack)
_result = "Posted back";
else
_result = "Loaded";

Form has the following code:

<html>
<head>
    <title>WebForm1</title>
    <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
    <meta name="CODE_LANGUAGE" Content="C#">
    <meta name=vs_defaultClientScript content="JavaScript">
    <meta name=vs_targetSchema
content="http://schemas.microsoft.com/intellisense/ie5">
</head>
<body MS_POSITIONING="GridLayout">
    <Form method="POST" name="ScheduleApptForm" id="ScheduleApptForm"
runat="server">
    This is Test Control display content!!!! Result : <%=_result%>
    <br>
    <asp:Button class="ScheduleApptFormSubmit" id="_btnSend"
        runat="server" Height="21" text="Schedule Your Appointment"
TabIndex="18"></asp:Button></TD>
    </Form>
</body>
</html>

Everything works fine until I have added in Global, Application_BeginRequest
following code:

Server.Transfer("WebForm1.aspx"); // or any other form name. Just trying to
transfer form to itself.

And thatâ€™s it. IsPostBack returns incorrect value. This issue definitely the
one mentioned in
http://support.microsoft.com/default.aspx?scid=kb;EN-US;821758 and should be
fixed two years ago. I have reinstalled Microsoft .NET Framework 1.1 Service
Pack 1. It doesnâ€™t help. Any idea or suggestion of what I did wrong? Does it
mean that Service Pack installed incorectly?

Regards,
Alex.

I think you have misunderstood what Server.Transfer does. Based on what you
have said, I would recommend using Response.Redirect instead. For more
details, try visiting the following site:

Hello Nathan,

Thanks for the replay :-). I know what Server.Transfer does and what
Response.Redirect does. I donâ€™t need to redirect my request to new URL (by
301, 302 or any other reason). I just want the different pages handle
different requests based on parameters on SERVER SIDE. Client (browser)
should not be aware of this internal process. (I.E. supporting such
functionality as â€˜skinsâ€™ as so on). But any way, my question is not why I
have to use Server.Transfer. The question is why IsPostBack is not
initialized correctly after Server.Transfer call, but should be accordingly
to 'http://support.microsoft.com/default.aspx?scid=kb;EN-US;821758'.
By the way I have reinstalled Microsoft .NET Framework 1.1 Service Pack 1
twise. (that hot fix is included in Servise Pack)

Thanks for the attempt to help.

Regards,
Alex.
