Hello Manoj,
This one is very hard to tell. Are you using some sort of caching? Or maybe the browser uses GET caching (so you need to add time stamp to the URL you are opening with javascript). Where are you binding the grid - are you using InitializeDataSource, etc.
It is really tough to tell without seeing the implmentation details first. By the way, I can recommend using our own WebDialogWindow component instead of window.open - much better results (better interface, better programmatic control over the window, skins, etc) - you can see WebDialogWindow in action here:

You mean you cannot attach a zip file to a message ?? Please check again because if you look on this forum, there are many posted messages containing full projects with source code in a .zip file.
Regarding browser caching of web forms, just hit google.com, right ? You will find how to do it in a matter of seconds:
http://dotnet.org.za/jase/pages/3762.aspx
protected void Page_Init(object sender, EventArgs e)
{
// make sure the page is not cached
Response.Expires = 0;
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");
}
