Hi,
Apply following css to your grid header and footer
fixedheader
{
background: url('Images/sprite.png') repeat-x 0px 0px;
background-color: Gray;
border-color: #989898 #cbcbcb #989898 #989898;
border-style: solid solid solid none;
border-width: 1px 1px 1px medium;
color: #000;
padding: 4px 5px 4px 10px;
vertical-align: bottom;
position: relative;
top: expression(this.parentNode.parentNode.parentNode.scrollTop-2);
left: expression(this.parentNode.parentNode.parentNode.scrollLeft);
}
and place following tag in your page head section
<meta http-equiv="X-UA-Compatible" content="IE=7" />
The above is working fine for me
Hope this helps.
