下面一个例子：在gridview中第一列输入数值，第二列输入数值，点击第三列的时候进行计算 求和，如果不符合标记为红色字体。
如图：
代码 ：
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
function setClf(con) {
var table = document.getElementById("GridView1");
var tr = table.getElementsByTagName("tr");
//获取鼠标点击的元素
var e = event.srcElement;
//获取元素所在的行的行号（表头行号从0开始）。注意：parentElement只适用于IE浏览器，而parentNode则符合DOM标准。
//var rowIndex=e.parentElement.parentElement.rowIndex ;
var i = e.parentNode.parentNode.rowIndex; //获取GridView控件 分别获取选定行指定列的值
var a, b,c;
a = parseFloat(tr[i].getElementsByTagName("td")[0].getElementsByTagName("input")[0].value);
b = parseFloat(tr[i].getElementsByTagName("td")[1].getElementsByTagName("input")[0].value);
//上面为获取gridview中textbox的，如果为lable则如下写法
// b = parseFloat(tr[i].getElementsByTagName("td")[1].getElementsByTagName("span")[0].innerText);
sum1 = a+b; //计算方法改变
c = parseFloat(tr[i].getElementsByTagName("td")[2].getElementsByTagName("input")[0].value);
if (sum1 != c) {
con.style.color = "Red";
}
else con.style.color = "black";
}
</script>
</head>

后台：
protected void Page_Load(object sender, EventArgs e)
{
DataTable newdtb = new DataTable();
newdtb.Columns.Add("BNDJ");
newdtb.Columns.Add("BNDY");
newdtb.Columns.Add("BNLJ");
for (int i = 1; i < 11; i++)
{
DataRow newRow = newdtb.NewRow();
//newRow["BNDJ"] = "pro" + i.ToString();
//newRow["BNDY"] = 12.3m;
newdtb.Rows.Add(newRow);
}
GridView1.DataSource = newdtb;
GridView1.DataBind();
}
