ASPX (c# behind) Value Passing Between Page Not Working

I my default.aspx have the following code in a page:

Label1.Text = datatable.Rows[0].Field<string>(1);

Response.Redirect("Welcome.aspx?Parameter=" + Label1.Text);

In my welcome.aspx page, I have the following page_load code:

 protected void Page_Load(object sender, EventArgs e)
        {
            Label2.Text = Request.QueryString["Parameter"].ToString() + ", welcome to the website!";
        }

When I view the website in a browser, on the Welcome page, I can see in the URL, that the parameter has been passed, however the label text is not updated. It almost seems like the page_load code isn't being run?

As requested, the aspx of the welcome page is below:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <style type="text/css">
        .auto-style1 {
            width: 503px;
            height: 249px;
            margin-left: 67px;
        }
    </style>
</head>
<body>
    <form id="form2" runat="server">
    <div style="margin-left: 280px">

        <br />
        <br />
        <br />
        <img alt="" class="auto-style1" src="Logo.jpg" /><br />
        <br />
        <br />
        <asp:Label ID="Label2" runat="server">testing</asp:Label>
        <br />
        <br />
        <br />

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

Can anybody explain why, and how to fix it?

Session State could be a better choice for that particular scenario, because you will need it whenever user lands on the WelcomePage.

Session["Parameter"] = datatable.Rows[0].Field<string>(1); 
// Set a break point at Redirect, and check to make value is assigned 
// to Session["Parameter"] before redirecting.
Response.Redirect("Welcome.aspx");

protected void Page_Load(object sender, EventArgs e)
{
   Label2.Text = Session["Parameter"] + ", welcome to the website!"; 
}

Note: If the above solution doesn't solve the problem, the worst case you just delete Welcome.aspx, create a new one without Master Page, and see Page_Load event fires.
