Please Wait Functionality ?

I have a page that takes a long time to process. I would like to
display a <div> for the client at the beginning of the page load, and
then when processing is complete get rid of the div and display my
page.

In my Page_Load:

HttpContext.Current.Response.Write(
"<div id=\"divSmartRemark\" style=\"position:absolute;
overflow:visible; text-align:center; width:240px; height:182px;
z-index:1; left:25; top:18;font-family:Tahoma; font-size:10pt;
font-weight:bold; color: red;
background-color:#FFFFFA\"><br/><br/><br/> please wait </div>");

Now what can I do to get rid of that by the time the page is otherwise
fully rendered?

Thanks.
 
The problem with your design is that the response is buffered until the page
is processed completely. And there is nothing you can do to change this.

What you can try to do is write the "Please Wait" message before the request
is sent and hope that the browser will not replace it with blank page during
the processing of the request.

Hi Localhost,
