How to delete an occurrence from the recurrence appointment series in WinUI Scheduler (Calendar)
In the WinUI Scheduler, delete an occurrence from the recurrence appointment series by using the RecurrenceExceptionDates property of the ScheduleAppointment.
C#
Add the appointments for the scheduler with the RecurrenceExpcetionDates property of the appointments.
public class SchedulerViewModel : INotifyPropertyChanged
{
private ScheduleAppointmentCollection scheduleAppointmentCollection;
public SchedulerViewModel()
{
var exceptionDate = new DateTime(2021, 06, 29);
this.ScheduleAppointmentCollection = new ScheduleAppointmentCollection();
var scheduleAppointment = new ScheduleAppointment()
{
Id = 1,
StartTime = new DateTime(2021, 06, 24, 10, 0, 0),
EndTime = new DateTime(2021, 06, 24, 12, 0, 0),
Subject = "Meeting",
RecurrenceRule = "FREQ=DAILY;INTERVAL=1;COUNT=10",
RecurrenceExceptionDates = new ObservableCollection<DateTime>() { exceptionDate }
};
ScheduleAppointmentCollection.Add(scheduleAppointment);
}
public ScheduleAppointmentCollection ScheduleAppointmentCollection
{
get
{
return this.scheduleAppointmentCollection;
}
set
{
this.scheduleAppointmentCollection = value;
this.RaiseOnPropertyChanged("ScheduleAppointmentCollection");
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void RaiseOnPropertyChanged(string propertyName)
{
this.PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
XAML
Bind the Appointments to the ItemsSource property of the Scheduler.
<scheduler:SfScheduler x:Name="Schedule"
FirstDayOfWeek="Monday"
ViewType="Week"
ItemsSource="{Binding ScheduleAppointmentCollection}">
</scheduler:SfScheduler>
