Thankyou fro your replies.
Thankyou verymuch for your help but what do you think about a more structured managment of active/focused view?
A toolbar is related to all the application but in one application there could be more regionsso...more than one active view.
Anyway only one region is "realy" active because it have the input focus in a child control
So i was thinkling to "something" that can live "crosswise" respect regions and all application views.
Something that can manage the real active view and notify events to toolbar or to other objects.
I am just thinking and searching a way to solve this problem so there could be other wrong hypothesis that i am doing.
Anyway what do you think about applicontion controller for this purpose is it wrong? Is there any other better system or suggested from PRISM team?
I can't find nothing about this problems in PRISM quick start.
