  1. Try this… Set the output to unbuffered (Response.BufferOutput), and include some javascript in your page that updates the UI as you see appropriate. For example, it might update a SPAN with a percentage complete or the details of the record you are processing. Then in your server code, output <script> tags that call the Javascript function from the Render override. Make sure you call Flush() at the appropriate times, and also Flush the base code after it Renders… The JS function calls should get sent down at the appropriate times and executed on the client, resulting in an updating page.

    For example… Your HTML page might look like this:

    <%@ Page Language='C#' AutoEventWireup='true' CodeBehind='Default.aspx.cs' Inherits='WebApplication1._Default' %>  <!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>  <html xmlns='http://www.w3.org/1999/xhtml' > <head runat='server'>     <title></title>     <script type='text/javascript'>         function UpdateScreen(t) {             document.getElementById('output').innerHTML = t;         }     </script> </head> <body>     <form id='form1' runat='server'>     <div>         <div id='output'></div>     </div>     </form> </body> </html> <script type='text/javascript'>     UpdateScreen('hello'); </script>

    and your codebehind will look like this:

    using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Threading;  namespace WebApplication1 {     public partial class _Default : System.Web.UI.Page     {         protected void Page_Load(object sender, EventArgs e)         {          }          protected override void Render(HtmlTextWriter writer)         {             Response.BufferOutput = false;              base.Render(writer);             Response.Flush();              for (int i = 0; i < 10; i++)             {                 Thread.Sleep(1000);                 Response.Write(string.Format('<script type='text/javascript'>UpdateScreen('{0}');</script>', i * 10));                 Response.Flush();             }         }     } }
