Hi Dave,
Thank you for your post.
Based on my understanding, your question is how to cause another postback
upon page's first load. If I've misunderstood anything, please feel free to
post here.
You can do this by registering a startup script to cause the form to submit
again.
For example, use following WebForm:
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" Text="Please
wait..."></asp:Label> </div>
</form>
Handle its Load event:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ClientScript.RegisterStartupScript(GetType(), "postback",
"document.forms[0].submit();", true);
} else
{
// simulate a lengthy operation
System.Threading.Thread.Sleep(5000);
// hide the "please wait" prompt
Label1.Visible = false;
}
}
Also, you may find following article useful:

Hope this helps. Please feel free to post here if anything is unclear.
