如何将非命令菜单项与基于命令的菜单项进行数据绑定以保持一致?

它可以正常工作,也许你忘记设置CanExecute标志或有其他依赖关系

完整代码

<Window x:Class="MenuBinding.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.CommandBindings>
    <CommandBinding Command="Open"
                Executed="CommandBinding_Executed"
                CanExecute="CommandBinding_CanExecute"/>
</Window.CommandBindings>
<Grid>
    <Menu>
        <MenuItem Name="mnuOpen"  Command="Open" IsEnabled="False" />
        <MenuItem Name="mnuExplorer" Header="Open Containing Folder" IsEnabled="{Binding ElementName=mnuOpen, Path=IsEnabled}" />
    </Menu>
</Grid>

和阶级

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
    {
        MessageBox.Show("Magic");
    }

    private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e)
    {
        e.CanExecute = true; //define if command can be executed
    }
}
