c# - how to handle PageRequestManagerTimeoutException in ASP.net Web Application?

I am working on a ASP.NET web application that tryies to download some files from a remote server by login the server. While I try to download a file it works fine with small files but a It shows following exception while downloading a file of 750 KB.

I m defining the HTTPRequest Timout = System.Threading.Timeout.Infinite;

I m reading the files from server using this code

byte[] buffer = new byte[32768];
            using (Stream input = getResponse.GetResponseStream())
            {
                using (FileStream output = new FileStream(saveTo1, FileMode.OpenOrCreate))
                {
                    int bytesRead;

                    while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0)
                    {
                        output.Write(buffer, 0, bytesRead);
                    }
                }
            }

What could possible be creating this problem?

Also When I click on Ignore or Continue It continues the download smoothly further. How can I overe this problem?

Thanks in Advance. :)

If you need to handle the timeout exception, you can handle it with javascript. Add this to your page.

<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(requestEndHandler );

// This function will handle the end request event
function requestEndHandler(sender, args) {
   if( args.get_error() ){
      document.getElementById("errorMessageLabel").innerText = 
         args.get_error().description;
       args.set_errorHandled(true);
   }
}

</script>
...

<span id="errorMessageLabel"></span>

Also if you want, you can increase AsyncPostBackTimeOut by sdding AsyncPostBackTimeOut="600"//Time to your script manager.:

<asp:ScriptManager ID="ScriptManager1" runat="server"

AsyncPostBackTimeOut="600" >

</asp:ScriptManager>
