相信C# .net 的程序员们都期待一个；强大的冻结行，冻结列的js 插件；
下面我为大家献上
一、aspx页面：
引用 js 和 css (注意 jquery )是必须的
<link href="GridviewScroll.css" rel="stylesheet" />
<script src="Scripts/jquery-1.6.2.min.js"></script>
<script src="Scripts/gridviewScroll.min.js"></script>
function gridviewScroll() {
$('#<%=dataGrid.ClientID%>').gridviewScroll({
width: pageWidth(),//获取当前页面宽度
height: 31+11*29,
freezesize: 3
});
}
$(document).ready(function () {
gridviewScroll();
});
$(window).resize(function () {
gridviewScroll();
});freezesize,是冻结行的列数
<asp:GridView ID="dataGrid" runat="server" AutoGenerateColumns="False" Width="100%">注意样式：一定要写正确
<Columns>
</Columns>
<HeaderStyle CssClass="GridviewScrollC3Header" />
<RowStyle CssClass="GridviewScrollC3Item" />
<PagerStyle CssClass="GridviewScrollC3Pager" />
<AlternatingRowStyle CssClass="GridviewScrollC3Item2 " />
</asp:GridView>
二、javaScript 脚本：gridviewScroll.min.js
