鼠标划过gridview的某一栏...?
鼠标划过gridview的某一栏位“test”时，显示div，如何让div的位置无论什么情况都位于栏位“test”正下方？

<script>
function ShowTip(id)
{
document.body.style.cursor = "wait ";
document.getElementById( "lbTest ").style.visibility = "visible ";

}
function HideTip()
{
document.body.style.cursor = " ";
document.getElementById( "lbTest ").style.visibility = "hidden ";
}
<script>
前台：
<div id= "lbTest " runat= "server " style= "BORDER-RIGHT: #ffffff 1px solid; BORDER-TOP: #ffffff

1px solid; Z-INDEX: 101; LEFT: 420px; BORDER-LEFT: #ffffff 1px solid; WIDTH: 240px;

BORDER-BOTTOM: #ffffff 1px solid; POSITION: absolute; TOP: 165px; BACKGROUND-COLOR:

#eeeeee; zOrder: 2000;color:red; font-size: 9pt; ">
aaaaaaaaaaaaaaaaa </div>

后台：
e.Row.Cells[5].Attributes.Add( "onmouseover ", "javascript:ShowTip( ' " + "lbTest " + " ') ");
e.Row.Cells[5].Attributes.Add( "onmouseout ", "javascript:HideTip() ");

[解决办法]
鼠标过那一栏时记录下坐标位置，然后把div放置相应位置
