At your `Button` you can also bind a property called `CommandParameter`. This value will be passed to your command-handler — Tomtom, Jun 28 '16 at 06:09

If you are that particular to pass the button element to viewmodel You can use below code :

 CommandParameter="{Binding ElementName=YourButtonName}"

You could even pass the entire window, user control, or a particular list or list item to the view model

 CommandParameter="{Binding ElementName=YourWindow}"     
 CommandParameter="{Binding ElementName=Control}"
