Question

I’m working on a singleton Applicatiobar, so I can access it from every class that inherites PhoneApplicationPage, but I want to add a Canvas( or any other UIElement ) to the basic UI, so it must be available through the entire application. Instead of saying:
CollectionName.Children.Add( UIElement ) Is there a single class from where I can acces all the elements on the currently active page and add/ remove UIElements?

You have acces to PhoneApplicationFrame:

 (App.Current.RootVisual as PhoneApplicationFrame)

Current page you can get with:

var currentPage = ((App)Application.Current).RootFrame.Content as PhoneApplicationPage;
