I have implemented the client-side event OnClientAppointmentDataBound to set property cssClass of RadScheduler appointments:
app = args.get_appointment();
If the custom attribute "RegisteredMembers" is not empty, property cssClass is set accordingly.
The problem is that, differently from the RadScheduler screen shot displayed on page http://www.telerik.com/help/aspnet-ajax/scheduler-appearance-setting-appointment-style.html
, the border of the appointments are not set to yellow; only the background of the appointments are (see attachment).
What am I missing?
