Updating the user
<p>I am having a grid in gridpage.aspx and on clicking the search button in gridpage.aspx. it opens a search popupwindow  with search criteria and  after entering the search criteria and clicking the search button in the popup window  will close the popup window and displays all the records in the gridpage.aspx.</p>

<p>the scenario is when i am retreiving lakhs of records i want to display the user with some update  that the search is still in progress </p>
