Невозможно запустить rptvwrclinicwsieapointmentcount.localreport.subreportprocessing += new subreportprocessingeventhandler(subreport_appointmentmonthcount); событие

---

При создании вложенного отчета через RDLC в C# asp.net в веб-приложении я обнаружил ошибку, связанную с

RptVwrClinicWsieApointmentCount.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(Subreport_AppointmentMonthCount);


Я попробовал следующий ниже упомянутый код... Пожалуйста, подскажите мне, что еще мне нужно, чтобы удалить следующую ошибку :-

Что я уже пробовал:
