title: Group filtering in Crystal Reports
body: <p>In Crystal Report Designer in VS 2008, I can go to the crystal reports menu, report, Selection Formula, Group and enter a filter formula to filter on a group level. This means I can filter to only show records for a certain account, but my group levels show the totals for all records, which is what I want.</p>
  
  <p>However, when I come to add my filter dynamical in my C# code, the only option I get to use is </p>
  
  <pre><code>CRViewer.SelectFormualr= .....
  </code></pre>
  
  <p>This does the record type filtering, not group type. Is there any way to do group level filtering?</p>
