Add following code at client side
<script>
function setscroll()
{
var gridCol = document.getElementById("GridView1").getElementsByTagName("td")
if(gridCol.length > 0)
{
var rowCOunt = 0;
while(rowCOunt < gridCol.length)
{
if(gridCol[rowCOunt].style.backgroundColor=="red")
{
window.scrollTo(0,gridCol[rowCOunt].offsetTop);
break;
}
rowCOunt +=1;
}
}
}
</script>
ad call this function in page body on load
