在MVVM Light应用程序中实现编辑菜单

我正在使用MVVM Light构建WPF应用程序。我已经添加到我的窗口中的菜单，其中包括标准文件和编辑菜单：在MVVM Light应用程序中实现编辑菜单

<Window x:Class="ParserEditor.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:local="clr-namespace:ParserEditor" 
     xmlns:ignore="http://www.galasoft.ch/ignore" 
     xmlns:i="clr namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" 
     xmlns:cmd="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.WPF4" 
     mc:Ignorable="d ignore" 
     Closing="Window_Closing" 
     DataContext="{Binding Main, Source={StaticResource Locator}}" 
     Height="{Binding Height, Mode=TwoWay}" 
     MaxHeight="{Binding MaxHeight, Mode=TwoWay}" 
     MinHeight="{Binding MinHeight, Mode=TwoWay}" 
     MinWidth="450" 
     Width="450" 
     Title="{Binding WindowTitle}"> 

    <Window.InputBindings> 
     <KeyBinding Command="{Binding NewParserCommand}" Gesture="CTRL+N" /> 
     <KeyBinding Command="{Binding OpenParserCommand}" Gesture="CTRL+O" /> 
     <KeyBinding Command="{Binding SaveParserCommand}" Gesture="CTRL+S" /> 
     <KeyBinding Command="{Binding SaveParserAsCommand}" Gesture="ALT+A" /> 
     <KeyBinding Command="{Binding ExitCommand}" Gesture="ALT+F4" /> 
     <KeyBinding Command="{Binding ApplicationCommands.Undo}" Gesture="CTRL+Z" /> 
     <KeyBinding Command="{Binding ApplicationCommands.Redo}" Gesture="CTRL+Y" /> 
     <KeyBinding Command="{Binding ApplicationCommands.Cut}" Gesture="CTRL+X" /> 
     <KeyBinding Command="{Binding ApplicationCommands.Copy}" Gesture="CTRL+C" /> 
     <KeyBinding Command="{Binding ApplicationCommands.Paste}" Gesture="CTRL+V" /> 
     <KeyBinding Command="{Binding ApplicationCommands.Delete}" Gesture="DEL" /> 
     <KeyBinding Command="{Binding ApplicationCommands.SelectAll}" Gesture="CTRL+A" /> 
    </Window.InputBindings> 

    <DockPanel Name="Dock"> 
     <Menu IsMainMenu="true" DockPanel.Dock="Top"> 
      <MenuItem Header="_File"> 
       <MenuItem Header="_New..." InputGestureText="Ctrl-N" Command="{Binding NewParserCommand}" /> 
       <MenuItem Header="_Open..." InputGestureText="Ctrl-O" Command="{Binding OpenParserCommand}" /> 
       <MenuItem Header="_Save..." InputGestureText="Ctrl-S" Command="{Binding SaveParserCommand}" /> 
       <MenuItem Header="Save _As..." InputGestureText="Alt-A" Command="{Binding SaveParserAsCommand}" /> 
       <Separator /> 
       <MenuItem Header="E_xit" InputGestureText="Alt-F4" Command="{Binding ExitCommand}" /> 
      </MenuItem> 
      <MenuItem Header="_Edit"> 
       <MenuItem Header="Undo" InputGestureText="Ctrl-Z" /> 
       <MenuItem Header="Redo" InputGestureText="Ctrl-Y" /> 
       <Separator/> 
       <MenuItem Header="Cut" InputGestureText="Ctrl-X" /> 
       <MenuItem Header="Copy" InputGestureText="Ctrl-C" /> 
       <MenuItem Header="Paste" InputGestureText="Ctrl-V" /> 
       <MenuItem Header="Delete" InputGestureText="Del" /> 
       <MenuItem Header="Select All" InputGestureText="Ctrl-A" /> 
      </MenuItem> 
     </Menu> 

     <Grid x:Name="LayoutRoot"> 
      <!-- Some controls, including TextBlocks & TextBoxes here -->    
     </Grid> 
    </DockPanel> 
</Window>

现在，如果我运行应用程序，并进行一些编辑在TextBox控件之一，我可以用通常的键盘短剪切，复制&粘贴文本，撤消&重做动作，而焦点是控制。但是，如果我点击我的编辑菜单，并使用我的选项之一，没有任何反应。

如何让我的菜单项正常工作？

我想通了。发布问题&查看XAML后，我发现编辑菜单项没有绑定任何命令。我将所需的Command="ApplicationCommands.xxx"语句添加到现在编辑菜单起作用的XAML &。
