    ' Group tasks by ProjectName...
    taskListView.GroupDescriptions.Add(New PropertyGroupDescription("ProjectName"))
    ' Then group by Complete status.
    taskListView.GroupDescriptions.Add(New PropertyGroupDescription("Complete"))
End If

if (taskListView.CanGroup == true)

    // Group tasks by ProjectName...
