title: IsLoaded property for a UserControl in WinRT
body: <p>It looks as if there is no <code>IsLoaded</code> property in a <code>UserControl</code> object in XAML, even if the <code>Loaded</code> event is there.</p>
  
  <p>But the <a href="http://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.isloaded%28v=vs.110%29.aspx" rel="nofollow">MSDN page on IsLoaded</a> tells that it should be there since <code>UserControl</code> derives from <code>FrameworkElement</code>.</p>
  
  <p>So I guess it was removed in XAML (the doc is for WPF). But I can't believe they just deleted it in WinRT, they must have replaced it with something else?</p>
  
  <p><strong>So, question</strong>:
  How do I gain access to the <code>IsLoaded</code> boolean of a <code>UserControl</code> in WinRT?</p>
  
  <p>Of course, it is always possible to do it by hand on every user control by registering a callback on the <code>Loaded</code> event, but it is a pain for such a simple thing.</p>
