asp.net - 当前上下文中不存在名称 'GridView1'

Question

我有两个名为 TimeSheet.aspx.cs 和 TimSheet.aspx 的文件，下面给出了文件的代码供您引用。

当我构建应用程序时，我收到错误“名称'GridView1'在当前上下文中不存在”，即使我有一个ID为GridView1的控件并且我也添加了runat =“server”。

我无法弄清楚是什么导致了这个问题。任何人都可以弄清楚这里发生了什么。

感谢和问候，

问题可能是 GridView1 没有自动添加到 Designer.cs 文件中。如果是这种情况，请手动将其添加到设计器中。
