Ah, Sorry - see that I used HorizontalAlignment in one version and HorizontalContentAlignment in the other :-{

If you might need this behaviour on the same type of control throughout the app then it's worth actually putting in it a resource dictionary. Main bonus of using a resource dictionary is that you can set application wide styles allowing you to change the overall appearance of the app in one place (ala CSS in html)
