title: How to pass a value between Silverlight pages for WP7?
body: <p>I've got a MainPage.xaml page a Detail.xaml page.</p>
  
  <p>I've passed variables to the Detail.xaml from MainPage.xaml by using a static variable and referencing it in Detail.xaml (the detail page is acting like a dialog). However once I've updated the content of another object, I want to call a method in MainPage.xaml to refresh the content of that page using the updated object from the Detail.xaml page.</p>
  
  <p>I assume I am not using the correct paradigm for this and should probably be using MVVM or something but I'm not familiar with the implementation and was hoping there was a simple way to do this?</p>
