Asp.net 锁定/冻结多行 Gridview 标题答案

【问题标题】：Asp.net Lock/Freeze Multi Row Gridview HeadersAsp.net 锁定/冻结多行 Gridview 标题
【发布时间】：2014-09-09 15:22:57
【问题描述】：

我一直在执行冻结我的 Gridview 上的标题的任务。 Gridview 也必须是可滚动的。我已经完成了滚动功能。我无法获得锁定标题功能。我尝试了各种解决方案，包括 css 样式和 JQuery 插件，但似乎没有任何效果。我认为最大的是我的 Gridview 有一个多行标题。我在 aspx 中定义了一个行标题，然后在 Gridview 行数据绑定事件中创建了第二个行标题。有什么有用的解决方案吗？

代码如下

aspx

<div style="height: 95%; overflow-y: auto;">

我想你正在寻找this。

这是我在我的应用程序中使用它的方法，它可以正常工作。对于类似的问题，请参考我在 SO 上的其他答案 here 和 here

function pageLoad(sender, args) {
   gridviewScroll ();
 }

 function gridviewScroll() {
    gridView1 = $('#GridView1').gridviewScroll({
       width: 915,

       onScrollVertical: function (delta) {
       // store the scroll offset outside of this function in a hidden field and restore if you want to maintain vertical scroll position
       },
      onScrollHorizontal: function (delta) {
        //store the scroll offset outside of this function in a hidden field and restore if you want to maintain horizontal scroll position
      }
    });
  }

以及关于冻结网格标题在我的应用程序中的外观的屏幕打印

【讨论】：

我之前尝试过使用gridviewScroll。它仅支持冻结/锁定 1 个标题行。我需要冻结 2 个可能 3 个标题行
@Jmunndi 您可以选择这样做。根据需要更改$('#GridView1').gridviewScroll({ .. 函数中headerrowcount: 2 或headerrowcount: 3 属性的值。
我玩得更多了，它开始融合在一起。我的问题是我使用 div 而不是插件来处理我的滚动。我仍然更喜欢这个选项，因为我在设置高度和宽度时遇到了麻烦。我不能使用固定的像素值，我必须使用百分比。当我将宽度设置为 100% 时，我的网格拍摄通过屏幕并启用水平滚动。我不要那个。垂直滚动没问题，但水平滚动不行。以百分比设置网格的高度和宽度有什么建议吗？
