    Hello,

    I've gone through the tutorial here: https://docs.telerik.com/devtools/winforms/scheduler/appointments-and-dialogs/adding-a-custom-field-to-the-editappointment-dialog

    I have been able to add my custom field to the scheduler, however, when I save the appointment and edit the same appointment again, the value I put in the "IdPaciente" field is not recovered, it simply recovers the empty value.
    But if you are saving in the database the field "IdPaciente"
    I'm seeing that in the LoadSettingsFromEvent method, IEvent the custom field retrieves empty. 
    What am I doing wrong, could you help me please?

     public partial class CustomAppointmentEditForm: Telerik.WinControls.UI.Scheduler.Dialogs.EditAppointmentDialog
        {
            public CustomAppointmentEditForm()
            {
                InitializeComponent();
            }

            protected override void LoadSettingsFromEvent(IEvent ev)
            {
                base.LoadSettingsFromEvent(ev);
                AppointmentWithIdPaciente appointmentWithIdPaciente = ev as AppointmentWithIdPaciente;

                if(appointmentWithIdPaciente != null)
                {
                    radTextBoxIdPaciente.Text = appointmentWithIdPaciente.IdPaciente;
                }
            }

            protected override void ApplySettingsToEvent(IEvent ev)
            {
                AppointmentWithIdPaciente appointmentWithIdPaciente = ev as AppointmentWithIdPaciente;
                if(appointmentWithIdPaciente != null)
                {
                    appointmentWithIdPaciente.IdPaciente = radTextBoxIdPaciente.Text;
                }
                base.ApplySettingsToEvent(ev);
            }
            protected override IEvent CreateNewEvent()
            {
                return new AppointmentWithIdPaciente();
            }
