title: Binding property from a property
body: <p>how can I do a bind if the property to show is a property from a property, like this case:</p>
  
  <p>Xaml:</p>
  
  <pre><code>&lt;TextBox Text="{Binding log.Message}"/&gt;  ????
  </code></pre>
  
  <p>In the class defined as Datacontext, I declare a log variable:</p>
  
  <pre><code>public Log log = new Log();
  </code></pre>
  
  <p>the Log class:</p>
  
  <pre><code>public class Log : INotifyPropertyChanged
  {
      public static string Message{ get { return message; } }
    ....
  </code></pre>
