The RadScheduler's AppointmentCreated
event and other events (AppointmentDataBound, AppointmentsPopulating) fire after PreRender because of the data binding, which occurs after PreRender. If you need an event, which fires later in the page lifecycle than AppointmentCreated
you can use the PreRenderComplete event . All of the above-mentioned RadScheduler events fire between PreRender and PreRenderComplete.
