I have an 'Export' button on my page, when clicking this button, a file is
streamed to the client like this :

lblMessage.Text = "Thank you for downloading...";
System.IO.FileInfo objFI = new System.IO.FileInfo(FullFileName);
System.Web.HttpContext.Current.Response.Clear();
System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition",
"attachment; filename=" + DownloadFileName);
System.Web.HttpContext.Current.Response.AddHeader("Content-Length",
objFI.Length.ToString());
System.Web.HttpContext.Current.Response.ContentType =
"application/octet-stream";
System.Web.HttpContext.Current.Response.WriteFile(objFI.FullName);
System.Web.HttpContext.Current.Response.End();

This works perfectly but after downloading, the page on wich the
download/export was initiated doesn't update, the lblMessage isn't updated
as is a button wich should become visible after download. I'm not sure how
to accomplish this.

Could anyone point me in right direction.

TIA,
Jurjen.

When you replace the Response with a file download and call Response.End,
that's the end of the Response and you will get no more.

I'd try issuing the download from a popup window that uses a second page,
leaving your first page alone.
