Hi. Thanks for your answer, and sorry for the very late reply here.
In your example there is only 1 resource (room).
I found out that the Reaources sample in the demos, http://demos.telerik.com/kendo-ui/scheduler/resources
, shows my problem.
If I understand the demo right, it's the idea that the color of the events should reflect the meeting room.
This gives us the possible values og blue or pink, and a light blue if no room is choosen.
But if you don't choose a room and assign Charlie as an attendee, you get a green event in the scheduler, which is confusing/wrong.
This could of course be handled by not attaching colors to the attendees but that would be a "cheap" workaround :), since it is nice to have the attendee colors available in the edit window, and possible in a custom event/timeslot template.
I hope my problem is clearly described.
