title: DataGrid column bind to a item of the List
body: <p>The ItemsSource of DataGrid is a <code>List&lt;myClass&gt;</code>, and <code>myClass</code> has a <code>List&lt;int&gt;</code> Property.<br>
  Now I want to bind the first item of the <code>List&lt;int&gt;</code> to the first column of the DataGrid, and the second item to the second column.<br>
  How to do it?</p>
  
  <p>XMAL:</p>
  
  <pre><code>&lt;DataGrid.Columns&gt;
       &lt;DataGridTextColumn Header="MyClass Name" Binding="{Binding Name}" &gt;&lt;/DataGridTextColumn&gt;
       &lt;DataGridTextColumn Header="First Item of Numbers" Binding="{Binding ??}" &gt;&lt;/DataGridTextColumn&gt;
       &lt;DataGridTextColumn Header="Second Item of Numbers" Binding="{Binding ??}" &gt;&lt;/DataGridTextColumn&gt;                                         
  &lt;/DataGrid.Columns&gt;
  </code></pre>
  
  <p>c#:</p>
  
  <pre><code>class MyClass
  {            
          public string Name{ get; set; }
          public List&lt;int&gt; Numbers= new List&lt;int&gt;();
  }
  </code></pre>
