title: Updating App content on resume
body: <p>this is going to be a noob question but i wasn't able to successfully google it.</p>
  
  <p>In my windows phone app there's this method in App.xaml.cs</p>
  
  <pre><code>    private void Application_Activated(object sender, ActivatedEventArgs e)
      {
      }
  </code></pre>
  
  <p>That is called when my App is brought back from the background. How can i have my main app page (main.xaml.cs) update itself with new data from the web when this method is beeing called. I only want it to happen when my main page is open but not when other pages are open</p>
  
  <p>Can anyone give me a hint here?</p>
  
  <p>Thanks in advance!</p>
