  <p>There is a code like <code>RowHeaderStyle</code> in WPF Silverlight but I don't get it in desktop datagrid.</p>
  
  <pre><code>&lt;dg:DataGrid x:Name="dg"&gt;
    &lt;dg:DataGrid.RowGroupHeaderStyles&gt;
      &lt;Style... /&gt;
    &lt;/dg:DataGrid.RowGroupHeaderStyles&gt;
  &lt;/dg:DataGrid&gt;
  </code></pre>
  
  <p>It uses silverlight application. I'm still don't know how to do this in desktop datagrid using WPF.</p>
  
  <p>Any resources or way to create this? Help please..</p>
