This property is used to associate a command with a particular MenuItem instance. The following example associates the Copy command with a MenuItem and automatically supplies the input gesture text Ctrl+C. The example does not set the Header property, but the Header for the MenuItem is "Copy" at run time. You can specify another header for the MenuItem if you want it to be different. For information on how to bind to the desired command, see How to: Add a Command to a MenuItem.
