  Hi,
  I've been using the command manager based on the posted examples, but have been running into a problem lately. Sometimes the can execute property is not refreshing correctly. It refreshes on some situations, but sometimes it needs to be forced (by switching tabs for example). Is there a way to force by code a refresh so the can execute updates acordingly?
  
  Many thanks!

  Hello Sebastiano,
  
  To force invalidate on RoutedCommands you can call CommandManager InvalidateRequerySuggested() static method. Keep in mind that this can have negative impact on the performance of your application if a lot of routed commands are used.
  My recommendation is to check why commands are not invalidating correctly and if you think that they should invalidate then post here the scenario which is not working as expected.
