How to notify when an appointment reminder action changed in the WPF Scheduler (Calendar)

WPF Scheduler supports to notify the appointment reminders action such as dismiss, dismiss all, or snooze changed in the scheduler built-in reminder alert window.

STEP 1: To alert the appointment reminders in the scheduler, enable the reminder for the scheduler using the EnableReminder property.

 
    <schedule:SfScheduler x:Name="schedule" EnableReminder="True"/>

STEP 2: Add the reminders for an appointment using the ScheduleReminder, and the scheduler reminder alert window will be open on the appointment reminders time.

private void AddAppointments()
{
    this.Appointments = new ScheduleAppointmentCollection();
 
    var newEvent = new ScheduleAppointment();
    newEvent.Subject = "Meeting";
    newEvent.StartTime = new DateTime(2021, 06, 16, 10, 0, 0);
    newEvent.EndTime = new DateTime(2021, 06, 16, 11, 0, 0);
    newEvent.AppointmentBackground = Brushes.Green;
    newEvent.Reminders = new ObservableCollection<SchedulerReminder>
    {
        new SchedulerReminder { ReminderTimeInterval = new TimeSpan(0)},
    };
 
    var newEvent1 = new ScheduleAppointment();
    newEvent1.Subject = "Planning";
    newEvent1.StartTime = new DateTime(2021, 06, 16, 12, 0, 0);
    newEvent1.EndTime = new DateTime(2021, 06, 16, 13, 0, 0);
    newEvent1.AppointmentBackground = Brushes.Green;
    newEvent1.Reminders = new ObservableCollection<SchedulerReminder>
    {
        new SchedulerReminder { ReminderTimeInterval = new TimeSpan(0)},
    };
 
    var newEvent2 = new ScheduleAppointment();
    newEvent2.Subject = "Retrospective";
    newEvent2.StartTime = new DateTime(2021, 06, 16, 14, 0, 0);
    newEvent2.EndTime = new DateTime(2021, 06, 16, 15, 0, 0);
    newEvent2.AppointmentBackground = Brushes.Green;
    newEvent2.Reminders = new ObservableCollection<SchedulerReminder>
    {
        new SchedulerReminder { ReminderTimeInterval = new TimeSpan(0)},
    };
 
 
    this.Appointments.Add(newEvent);
    this.Appointments.Add(newEvent1);
    this.Appointments.Add(newEvent2);
}

STEP 3: ReminderAlertActionChanged event will be triggered while changing the alert actions such as Dismiss, Dismiss All, Snooze in the scheduler built-in reminder alert window.

Schedule.ReminderAlertActionChanged += OnScheduleReminderAlertActionChanged;

{
    if (e.ReminderAction == ReminderAction.Dismiss)
    {
        MessageBox.Show("Reminder alert action Dismiss clicked for appointment", "Reminder", MessageBoxButton.OK);
    }
    else if (e.ReminderAction == ReminderAction.DismissAll)
    {
        MessageBox.Show("Reminder alert action cancelled for all appointments", "Reminder", MessageBoxButton.OK);
    }
    else if (e.ReminderAction == ReminderAction.Snooze)
    {
        MessageBox.Show("Reminder alert action Snoozed", "Reminder", MessageBoxButton.OK);
