title: Summary row for a dynamic EXT.NET GridPanel
body: <p>I'm building an application that displays some results in a grid.
  The grid is created dynamically, in the C# code behind. I'm using the following code to display grouping on the grid. But I'd also like to have a summary row. I've tried this with a plugin but it doesn't seem to work.</p>
  
  <pre><code>private GroupingView group = new GroupingView();
  
  group.ID = "gv1";
  group.HideGroupedColumn = true;
  
  group.GroupTextTpl = "{text} ({[values.rs.length]} {[values.rs.length &gt; 1 ? \"Items\" : \"Item\"]})";
  group.EnableRowBody = true;
  
  GridPanelResults.View.Add(group);
  
  GroupingSummary gsPlugin = new GroupingSummary();
  
  GridPanelResults.Plugins.Add(gsPlugin);
  </code></pre>
  
  <p>This is the summary row I need

  <p>Any ideas?</p>
