Disable client click after one Appointment in RadScheduler

[Teja]

Hi, 

In Telerik RadScheduler, I need to design a model in which a client is accessed to schedule only once. Once he/she is scheduled, all the other Appointments are disabled and he cannot schedule more than once.
If he/ she wants to schedule again, then the previous appointment has to be deleted and then be scheduled at his/her convenience.
Any help is appreciated.

Hello Teja,

You can subscribe the OnClientAppointmentInserting event and try following code which prevents adding appointments more then once.

javascript:

function OnClientAppointmentInserting(sender, agrs)
   {
       if (sender.get_appointments().get_count() >= 1)
       {
          agrs.set_cancel(true);
          alert("Only One appointment is allowed");
       }
   }

Thanks,
Shinu.
