title: WPF DataGrid Virtualization with Grouping
body: <p>I'm using the <a href="http://wpf.codeplex.com/" rel="noreferrer">WPF DataGrid from CodePlex</a> and I need to get Virtualization to work with grouping. </p>
  
  <p>This <a href="https://stackoverflow.com/questions/1102029/wpf-listview-virtualization-grouping">question</a> is on topic and points to an <a href="http://code.msdn.microsoft.com/getwpfcode/Release/ProjectReleases.aspx?ReleaseId=1142" rel="noreferrer">MSDN Example</a> but it only covers ListControls with with simple (i.e. single 'column') DataTemplates. </p>
  
  <p>Grouping and Virtualization seems like a pretty common use case for a Grid. Is there a standard/recommended/simple way of getting this going?</p>
