<CollectionViewSource
x:Name="groupedItemsViewSource"
Source="{Binding Groups}"
IsSourceGrouped="true"
ItemsPath="Items"/>If I bind a ListBox to the same collection (Groups) in the same page I see the data at design time, so its something to do with the GridView and/or the CollectionViewSource.
You could set the Source for the design, here is an article explaining how: http://bit.ly/TacvU0
