Hello,
Thank you for contacting Telerik Support.
In this case I would suggest overriding the
AppointmentComparer class Compare method for comparing two appointments. This way you can sort your appointments they way you want. I am attaching a sample project that shows how you can sort your appointment by the text value of a "User" type resource .
Hope that this will be helpful.
Regards,
