Forms Data Controls :: Maintaining Scroll Bar Position With Javascript?

I have a scroll bar in GridView. I m maintaining scroll bar position with javascript. It is working fine.

I have one more datagrid in the same page. I want to apply same Javascript to that datagrid also. Here is the javascript I used.

<script language="javascript" type="text/javascript">
var scrollTop;
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args)
{
var m = document.getElementById('divexample2');
scrollTop=m.scrollTop;
}
function EndRequestHandler(sender, args)
{
var m = document.getElementById('divexample2');
m.scrollTop = scrollTop;
}
</script>
