A complete sample project is available at https://github.com/DevExpress-Examples/custom-form-custom-fields-and-custom-actions-on-reminder-alert-e382

Form1.cs

    // Handle this event to perform a custom action when a reminder alert is fired.
    schedulerStorage1.ReminderAlert += SchedulerStorage1_ReminderAlert;
    // Specify the interval at which the reminder is polled for alert.
    schedulerStorage1.RemindersCheckInterval = checkInterval * 1000;

    schedulerControl1.OptionsBehavior.ShowRemindersForm = false;
private void SchedulerStorage1_ReminderAlert(object sender, ReminderEventArgs e) {
    // Create a new appointment.
    Appointment app = schedulerStorage1.CreateAppointment(AppointmentType.Normal);
    app.Subject = "Created on alert from appointment w/Price = " + e.AlertNotifications[0].ActualAppointment.CustomFields["CustomPrice"];
    app.Start = e.AlertNotifications[0].ActualAppointment.Start.AddHours(2);
    app.Duration = TimeSpan.FromHours(4);
    schedulerStorage1.Appointments.Add(app);

    // Modify the appointment for which the alert is triggered.
    e.AlertNotifications[0].ActualAppointment.LabelKey = 3;

    // Prevent the event from being fired one more time.
    e.AlertNotifications[0].ActualAppointment.Reminder.Dismiss();
}
