GridView表头固定 滚动
搜到几个都没成功
1.孟子
<script type= "text/javascript ">
function s()
{
var t = document.getElementById( " <%=GridView1.ClientID%> ");
var t2 = t.cloneNode(true)
for(i = t2.rows.length -1;i > 0;i--)
t2.deleteRow(i)
t.deleteRow(0)
a.appendChild(t2)
}
window.onload = s()
</script>
<div id=a> </div>
这个t等于null

没搞成
3.最简单的一个
<style>
.Freezing
{
position:relative ;
table-layout:fixed;
top:expression(this.offsetParent.scrollTop);
left:expression(this.offsetParent.scrollLeft);
z-index: 10;
}
</style>
<HeaderStyle BackColor= "#cc0000 " Font-Bold= "True " CssClass= "Freezing " ForeColor= "#E7E7FF " />
这个基本可以，
但是 1.比如把网页缩小后表头移位
2.隐约能看到表体有一点点到了表头的上面
谁有好方法不
?
我的数据是动态绑定的

/*
合并且固定表头：
BUG：在IE6上滑动条移动后如表格内容中存在dropdownlist，则dropdownlist将与表格叠加，这个问题估计是IE6的BUG
前台：
(注意：DataGrid的HeaderStyle中加入这句CssClass= "Freezing ")
(注意：DataGrid的边框会存在白边，将边线颜色和表头背景颜色设为同一种颜色，BorderStyle= "None ")

switch (e.Item.ItemType)

case ListItemType.Header:
//第一行表头
TableCellCollection tcHeader = e.Item.Cells;

tcHeader.Add(new TableHeaderCell());

注意：DataGrid的边框会存在白边，将边线颜色和表头背景颜色设为同一种颜色，BorderStyle= "None ")
