Question

我有两个DataGrid在同一个位置，所以我只是在启动时隐藏其中一个。当我将编码设置为像这样的按钮时 DataGrid1.Visible = false; DataGrid2.Visible = true;

两个DataGrid都只是消失了。

我猜DataGrid1覆盖了DataGrid2，因此隐藏了DataGrid2。我尝试搜索从水中拉出DataGrid2的方式，但无法搜索它。

此外，我有两个按钮分配相同的位置。并按照与上述相同的方式进行。这两个按钮也会消失

Answer 1

您可以在datagrids上尝试BringToBack（）和SendToBack（）方法。

Answer 2

试试这个。这个对我有用。如果这不起作用，请设置断点，检查两个datagridView可见属性。

Answer 3

您可以做一件简单的事情，将两个数据网格放在两个不同的面板中，然后隐藏并显示该面板。它可以解决你的问题。

Answer 4

您是在服务器端的Button_Click（）事件处理程序中执行此操作吗？您可能需要在Page_Load（）事件中添加对IsPostBack的检查。

Answer 5

您可以尝试使用gridView1.BringToFront（）;

但是，请尝试使用TabControl。它具有更好的UI样式和内置的功能支持。
