title: Infragistics XamDataGrid Group By on load in WPF
body: <p>How can I set a Group By on Load for a given property for the XamDataGrid from Infragistics, and making the view of this uncollapsed with the ability to collapse the group disabled?
  If this is possible I would know how I can hide the Group By small button as well.</p>
  
  <p>My environment is WPF and C#.</p>
