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

2 mins read

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);
}

XAML

<Window.DataContext>
    <local:SchedulerViewModel/>

    {
        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);
