Thank you for writing.
Please refer to our Formatting appointments
help article which demonstrates how to style the AppointmentElements
. In the event handler you have access to the Appointment
via the SchedulerAppointmentEventArgs
. You should cast the SchedulerAppointmentEventArgs.Appointment
to your custom class, extract the custom field and apply the desired style to the SchedulerAppointmentEventArgs.AppointmentElement
I hope this information helps. Should you have further questions, I would be glad to help.
