title: When binding, is it possible to specify the path on the source object?
body: <p>In a given binding, is it possible to specify the <strong><em>path</em></strong> on the <strong><em>source</em></strong> object? </p>
  
  <p>It seems like this could avoid a lot of trivial converters.</p>
  
  <p>Imagine the following example:</p>
  
  <p><strong>C#:</strong></p>
  
  <pre><code>class foo
  {
     bool A
     int B
  }
  </code></pre>
  
  <p><strong>WPF:</strong></p>
  
  <pre><code>&lt;ComboBox
      ItemsSource="ListOfFoos" 
      SelectedItem="{Binding number, SourcePath=B}" /&gt;
  </code></pre>
