title: MvcContrib Grid sort on related object
body: <p>I want to do server side sorting of a related table using MvcContrib Grid</p>
  
  <p>I have</p>
  
  <pre><code> @Html.Grid(Model.Result).Columns(column =&gt;
  {
      column.For(u =&gt; u.Name).Named("Name");
      column.For(u =&gt; u.Country.Name).Named("Country").SortColumnName("Country");
   }).Sort(Model.GridSortOptions)
  </code></pre>
  
  <p>This displays the table/grid correctly. However I cannot sort by Country.Name I get an error</p>
  
  <p><strong>DbSortClause expressions must have a type that is order comparable</strong></p>
