How do I add a custom routed command in WPF?

Question

I have an application that contains Menu and sub menus. I have attached Appliocation Commands to some of the sub menu items such as Cut, Copy and Paste.
I also have some other menu items that do not have application commands.
How could I add a custom command binding to those sub menu items?
I have gone through this article but unable to attach event to my sub menu items.

I use a static class that I place after the Window1 class (or whatever the window class happens to be named) where I create instances of the RoutedUICommand class:

public static class Command {      public static readonly RoutedUICommand DoSomething = new RoutedUICommand("Do something", "DoSomething", typeof(Window1));     public static readonly RoutedUICommand SomeOtherAction = new RoutedUICommand("Some other action", "SomeOtherAction", typeof(Window1));     public static readonly RoutedUICommand MoreDeeds = new RoutedUICommand("More deeds", "MoreDeeeds", typeof(Window1));  } 

Add a namespace in the window markup, using the namespace that the Window1 class is in:

xmlns:w="clr-namespace:NameSpaceOfTheApplication" 

Now I can create bindings for the commands just as for the application commands:

<Window.CommandBindings>     <CommandBinding Command="ApplicationCommands.Open" Executed="CommandBinding_Open" />     <CommandBinding Command="ApplicationCommands.Paste" Executed="CommandBinding_Paste" />     <CommandBinding Command="w:Command.DoSomething" Executed="CommandBinding_DoSomething" />     <CommandBinding Command="w:Command.SomeOtherAction" Executed="CommandBinding_SomeOtherAction" />     <CommandBinding Command="w:Command.MoreDeeds" Executed="CommandBinding_MoreDeeds" /> </Window.CommandBindings> 

And use the bindings in a menu for example:

<MenuItem Name="Menu_DoSomething" Header="Do Something" Command="w:Command.DoSomething" />

Instead of defining them in a static class, you might as well declare the commands directly in XAML. Example (adapted from Guffas nice example):

<Window.Resources>     <RoutedUICommand x:Key="DoSomethingCommand" Text="Do Something" />     <RoutedUICommand x:Key="DoSomethingElseCommand" Text="Do Something Else" /> </Window.Resources> <Window.CommandBindings>     <CommandBinding Command="{StaticResource DoSomethingCommand}" Executed="CommandBinding_DoSomething" />     <CommandBinding Command="{StaticResource DoSomethingElseCommand}" Executed="CommandBinding_DoSomethingElse" /> </Window.CommandBindings> ... <MenuItem Name="Menu_DoSomething" Header="Do Something" Command="{StaticResource DoSomethingCommand}" />
