我在 Windows 窗体中创建了一个表格布局，如图所示，我在表格中添加了一个鼠标右键单击菜单，

我不想将子菜单项添加到以下菜单项中，例如
When i click add deviceit should show subitems such as sounder, MCP, strobeetc
When i click faultit should show subitems such as open circuit fault, sounder fault, `short circuit fault' so on
当我点击add device它应该显示子项，如sounder，MCP，strobe等当我点击fault它应该显示子项，例如open circuit fault，sounder fault`短路故障”等
This is how i created menuitems
这就是我创建菜单项的方式
ContextMenu m = new ContextMenu();
MenuItem addDevice = new MenuItem("Add Device");
MenuItem deleteDevice = new MenuItem("delete Device");
MenuItem fire = new MenuItem("Fire");
MenuItem fault = new MenuItem("Fault");
MenuItem suppress = new MenuItem("Suppress");
m.MenuItems.AddRange(new MenuItem[] { addDevice, deleteDevice, fire, fault,suppress});
tableLayout.ContextMenu = m;
m.Show((Control)(sender), e.Location);
The below is my form and table layout
下面是我的表格和表格布局

That format doesn't work for me. I'm forced to use:
这种格式对我不起作用。我被迫使用：
// People often exclude the applicable "using" statements--so samples don't work!
using System.Web.UI.WebControls;
// Create the MAIN menu item
MenuItem mnuMenuItem = new MenuItem();
// Create the SUB menu item
MenuItem mnuSubMenuItem = new MenuItem();
// Create the SUB menu item, "under" the MAIN menu item!
mnuMenuItem.ChildItems.Add(mnuSubMenuItem);

MenuItem newMenuItem1 = new MenuItem("Employee Master");
MenuItem mnuSubMenuItem = new MenuItem();
newMenuItem1.ChildItems.Add(mnuSubMenuItem);
mnuSubMenuItem.Text = "Add User...";
mnuSubMenuItem.NavigateUrl = "ADDURL.aspx";
MenuItem mnuSubMenuItem1 = new MenuItem();
newMenuItem1.ChildItems.Add(mnuSubMenuItem1);
mnuSubMenuItem1.Text = "Edit User...";
mnuSubMenuItem1.NavigateUrl = "EDITURL.aspx";
this.MenuMaster.Items.Add(newMenuItem1);
