The latest sandbox build now contains a demo page that shows a hierarchy of resources:

http://mvc.daypilot.org/sandbox/Calendar/DaysResources

The sources is a modified Calendar/Index example.

1. The following two lines are added to the view:

ViewType = DayPilot.Web.Mvc.Enums.Calendar.ViewType.Resources,
HeaderLevels = 2,

2. It adds the resources on the server side during the first automatic AJAX call (OnInit):

            protected override void OnInit(InitArgs initArgs)
            {
                UpdateWithMessage("Welcome!", CallBackUpdateType.Full);

                if (Id == "days_resources") // just applying it to DaysResources view
                {
                    Columns.Clear();
                    Column today = new Column(DateTime.Today.ToShortDateString(), DateTime.Today.ToString("s"));
                    today.Children.Add("A", "a", DateTime.Today);
                    today.Children.Add("B", "b", DateTime.Today);
                    Columns.Add(today);

                    Column tomorrow = new Column(DateTime.Today.AddDays(1).ToShortDateString(), DateTime.Today.AddDays(1).ToString("s"));
                    tomorrow.Children.Add("A", "a", DateTime.Today.AddDays(1));
                    tomorrow.Children.Add("B", "b", DateTime.Today.AddDays(1));
                    Columns.Add(tomorrow);
                   
                }
            }
