I  selected a recurring appointment and chosen option edit this occurence(single occurence) and saved the detail,  it is throwing following error. 

System.NullReferenceException was unhandled by user code
  Message=Object reference not set to an instance of an object.
       at Telerik.Web.UI.Scheduling.AppointmentController.AttachRecurrenceException(Appointment parent, Appointment exceptionAppointment, DateTime explicitExceptionDate, ISchedulerInfo schedulerInfo)
       at Telerik.Web.UI.Scheduling.AppointmentController.UpdateException(Appointment modifiedAppointment, Appointment originalAppointment, ISchedulerInfo schedulerInfo)
       at Telerik.Web.UI.Scheduling.AppointmentController.UpdateAppointment(ISchedulerInfo schedulerInfo, Appointment originalAppointment, Appointment modifiedAppointment)
       at Telerik.Web.UI.WebServiceAppointmentController.CreateRecurrenceException[T](ISchedulerInfo schedulerInfo, T recurrenceExceptionData)
       at Telerik.Web.UI.WebServiceAppointmentController.CreateRecurrenceException(ISchedulerInfo schedulerInfo, AppointmentData recurrenceExceptionData)
       at CalendarTest.SchedulerWebService.CreateRecurrenceException(MySchedulerInfo schedulerInfo, AppointmentData recurrenceExceptionData) in D:\dotnet Practice\CalendarTest\SchedulerWebService.asmx.cs:line 77

Not sure what is causing problem. The line number 77 is referring to following code:

return Controller.CreateRecurrenceException(schedulerInfo, recurrenceExceptionData);

Hi Pratap,

You can refer to this forum thread where similar issue have been discussed. If the suggestions there   doesn't help you or your case is somehow different please paste the code that is connected with RadScheduler in your case so we can be able to inspect it. 

Hope this will be helpful.

All the best,
