如何在子元素上禁用 ContextMenu？

Question

我想在網格中的子控件上禁用 ContextMenu，但是當用戶單擊元素之間的邊距區域中的網格時，必須看起來是 ContextMenu。

我有這個代碼：

<Grid Background="Transparent">
    <Grid.ContextMenu>
        <ContextMenu>
            <MenuItem Header="Item1"/>
            <MenuItem Header="Item2"/>
        </ContextMenu>
    </Grid.ContextMenu>

    <!-- Just example. In future will some collections -->
    <StackPanel>
        <Button Content="123" ContextMenuService.IsEnabled="False"/>
    </StackPanel>
</Grid>

用戶控件.xaml

<UserControl.Resources>
    <ContextMenu x:Key="AmazingMenu">
        <MenuItem Header="Item1"/>
        <MenuItem Header="Item2"/>
    </ContextMenu>
</UserControl.Resources>

<Grid x:Name="MegaGrid" Background="Transparent" MouseRightButtonDown="Grid_MouseRightButtonDown">
    <!-- Some controls -->
</Grid>

用戶控件.xaml.cs

private void Grid_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
{
    var control = e.OriginalSource as Grid;

    if (control.Name.Equals("MegaGrid"))
    {
        MegaGrid.ContextMenu = FindResource("AmazingMenu") as ContextMenu;
    }
    else
    {
        MegaGrid.ContextMenu = null;
    }
}
