title: Grouping in DataGrid bound to a *sample* data source (using Silverlight “Data” window)
body: <p>Silverlight 5 question. I can group items in a DataGrid by using PagedCollectionView as its ItemsSource (via GroupDescriptions.Add). No problem. However, we are designers (not experienced programmers) working on a prototype and are using the Blend “Data” window extensively where we can conveniently create sample data sources / collections and sample enter data. Unfortunately, GroupDescriptions.Add doesn’t seem to work on these xml-based collections created through the “Data” window. </p>
  
  <p>Is there a way to use grouping in DataGrid without having to use C#? Or is there a way to group the sample data created through the “Data” window in a DataGrid?</p>
  
  <p>I did my research and I'm starting to think this may not be possible. My first post, go easy on me! Thanks -</p>
