C# 与委托匹配的方法没有重载'；System.EventHandler
我正在合并Gridview列标题中的两行。这一行必须分类。要将排序功能添加到列标题，我需要将LinkButton控件添加到TableCell，然后将排序方法分配给click事件。我得到了“SectionGridView\u排序无重载…”我不知道如何将事件添加到单击操作中。代码如下：C# 与委托匹配的方法没有重载'；System.EventHandler,c#,gridview,merge,row,gridview-sorting,C#,Gridview,Merge,Row,Gridview Sorting,我正在合并Gridview列标题中的两行。这一行必须分类。要将排序功能添加到列标题，我需要将LinkButton控件添加到TableCell，然后将排序方法分配给click事件。我得到了“SectionGridView\u排序无重载…”我不知道如何将事件添加到单击操作中。代码如下： TableCell cellSecID = new TableHeaderCell(); cellSecID.HorizontalAlign = HorizontalAlign.Ce
