Freeze gridview pager while scrolling vertically - asp.net

Question

I have a gridview.
I have to implement both Paging as well as make the page scrollable both horizontally and vertically. The page navigation bar comes at the bottom.
While scrolling the page vertically, I want two things -
The gridview headers should also be frozen.
gridview pagers should also be frozen.
I mean they should not scroll along with the data.
Only the rows should scroll.
I have implemented -
1. Fixed header using CSS
2. Horizontally scrollable using CSS
3. Vertically scrollable using CSS
I am not able to
1. Fix the Pager.
My code:
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<style type="text/css">
div#gvResultStyle
{
width: 500px;
height: 350px;
overflow: scroll;
position: relative;
}
div#gvResultStyle th
{
background-color: Navy;
color: White;
top: expression(document.getElementById("gvResultStyle").scrollTop-2);
left: expression(parentNode.scrollLeft);
position: relative;
z-index: 20;
}
.gvPager
{
left: 0px;
width: 400px;
border-right-style: solid;
position: absolute;
height: 10px;
text-align: left;
border-right-color: Navy;
}
</style>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
