title: Handling a bubbling event raised from a modal dialog in main window
body: <p>I have a modal dialog in my WPF application that allows a user to login to a server. The dialog simply contains a User Control that handles all the login stuff (UI, web service call, and raising a routed event when the call returns).</p>
  
  <p>All works nicely and I can handle my event in the dialog (close the dialog when login successfull). However, I am not able to handle the event in my main application (I should refresh the UI once the user has logged in).</p>
  
  <p>How can one intercept such routed events outside the window where it has been raised (if even possible)? If not possible, what is the usual way to handle that?</p>
