Question

如何在asp.net网格视图中冻结最左边的2-3列？因此，当水平滚动时，将始终显示已冻结的初始2 - 3列。

任何答案??

Answer 1

是的，似乎有可能使用一些css魔法，在不同的z索引上使用固定和可滚动的列来保持固定在顶部。需要注意的是overflow:scroll可能不是100％便携式（我已在IE 8/9和Chrome FWIW上测试过）。

看看这个jsFiddle here

我用来生成GridView的ASPX在下面。

分别注意固定和滚动列的css类pinned和scrollable（应用于标题和项目）

但真正的工作是在css中完成的。请特别注意，您需要摆弄以使列宽正确以对齐左侧的固定td / th。

我写了jQuery插件可以修复header和freeze列，它可以应用于GridView。看图像：

可能你错过了剧本

    <script type="text/javascript" src="../Scripts/gridviewScroll.min.js"></script>

这个脚本就在这里。

屏幕尺寸的宽度u可以修改（44）

不要忘记放脚本
