is there any option to enable the click event for the Rad Scheduler Appointment Items?

Hello, Rick,  

According to the provided brief information, it seems that you want to detect when an appointment is clicked in RadScheduler. For this purpose, you can subscribe to the RadScheduler.MouseClick event and detect the element under the mouse:

        private void radScheduler1_MouseClick(object sender, MouseEventArgs e)
        {
            AppointmentElement appointmentElement = this.radScheduler1.ElementTree.GetElementAtPoint(e.Location) as AppointmentElement;
            if (appointmentElement!=null)
            {
                //TODO
            }
        }

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
