I am afraid that RadScheduler control does not support grouping by date and resource when WebService
binding is used for populating appointments. This is our RadScheduler control limitation and there is not workaround in this case.
I would recommend using grouping by resource and the RadScheduler Timelineview,
which gives you ability to customize your date headers and the number of slots to be displayed.
You could find more information about customization the RadScheduler Timelineview here
Please excuse us for our RadScheduler limitation.
