如何同时在窗口上显示两个 ContextMenu？

这是我的课

 public partial class Window1 : Window
    {
        ContextMenu contextMenu1 = new ContextMenu();
        ContextMenu contextMenu2 = new ContextMenu();
        public Window1()
        {
            InitializeComponent();
            contextMenu1.Items.Add("Hello1");
            contextMenu2.Items.Add("Hello2");

            contextMenu1.Placement = System.Windows.Controls.Primitives.PlacementMode.Relative;
            contextMenu2.Placement = System.Windows.Controls.Primitives.PlacementMode.Relative;

            contextMenu1.PlacementTarget = rectangle1;
            contextMenu2.PlacementTarget = rectangle2;
            contextMenu1.StaysOpen = true;
            contextMenu2.StaysOpen = true;

        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            contextMenu1.IsOpen = true;
            contextMenu2.IsOpen = true;
        }
    }

How can I show two ContextMenu on my window at the same time?

this is my class

 public partial class Window1 : Window
    {
        ContextMenu contextMenu1 = new ContextMenu();
        ContextMenu contextMenu2 = new ContextMenu();
        public Window1()
        {
            InitializeComponent();
            contextMenu1.Items.Add("Hello1");
            contextMenu2.Items.Add("Hello2");

            contextMenu1.Placement = System.Windows.Controls.Primitives.PlacementMode.Relative;
            contextMenu2.Placement = System.Windows.Controls.Primitives.PlacementMode.Relative;

            contextMenu1.PlacementTarget = rectangle1;
            contextMenu2.PlacementTarget = rectangle2;
            contextMenu1.StaysOpen = true;
            contextMenu2.StaysOpen = true;

        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            contextMenu1.IsOpen = true;
            contextMenu2.IsOpen = true;
        }
    }

通常，当单击上下文菜单本身以外的其他位置时，上下文菜单将会消失。因此，同时打开两个上下文菜单将涉及一些特殊处理。

除此之外，这种设置很可能会让用户感到困惑。

也许您应该考虑其他选项（工具栏、属性面板、级联上下文菜单）

现在您已将代码添加到问题中，我更加担心这种方法。您想向用户提供什么？您应该简单地使用 Grids 或 DockPanels 而不是矩形，并向其中添加常规菜单：

    <DockPanel Width="200"
               Height="200">
        <Menu DockPanel.Dock="Top">
            <MenuItem Header="Hello1" />
        </Menu>
        <Grid />
    </DockPanel>
    <DockPanel Width="200"
               Height="200">
        <Menu DockPanel.Dock="Top">
            <MenuItem Header="Hello2" />
        </Menu>
        <Grid />
    </DockPanel>
</StackPanel>

Normally a context menu will disappear when clicking somewhere else than in the context menu itself. So having two context menus open at the same time will involve some special handling.

Besides that, this setup will most probably cause the user to be confused.

Perhaps you should consider an other option (toolbar, property panel, cascading context menu)

EDIT

Now that you added your code to the question I am even more worried about this approach. What are you trying to offer to the user? You should simply use Grids or DockPanels instead of rectangles and add regular Menus to them:

    <DockPanel Width="200"
               Height="200">
        <Menu DockPanel.Dock="Top">
            <MenuItem Header="Hello1" />
        </Menu>
        <Grid />
    </DockPanel>
    <DockPanel Width="200"
               Height="200">
        <Menu DockPanel.Dock="Top">
            <MenuItem Header="Hello2" />
        </Menu>
        <Grid />
    </DockPanel>
</StackPanel>
