   <schedule:SfScheduler.MonthView>
   <schedule:SchedulerMonthView AppointmentDisplayMode = "Indicator"
                                        AppointmentDisplayCount="3"
                                        NavigationDirection="Vertical"

Declaration

public ICommand QueryAppointmentsCommand { get; set; }

Property Value

Type	Description
System.Windows.Input.ICommand	The default value is `null`.

Remarks

The SchedulerQueryAppointmentsEventArgs passed as command parameter. This is used to load the appointments in on-demand for visible dates. Loading appointments in on-demand improves the loading performance when you have appointments ranging for multiple years. Once the ViewChanged event is raised, the query appointments command will be invoked. If an appointment has been added, deleted or updated within the visible dates, then the query appointments command will not be invoked. Since appointments were already loaded for that visible dates. The recurrence appointment should be added to the AppointmentsSource until the date of recurrence ends. If RecurrenceRule added with count or end date, you can use the GetDateTimeOccurrences(String, DateTime, Nullable<DateTime>, Nullable<DateTime>, Nullable<DateTime>, DayOfWeek) method to get recurrence date collection and compare recursive dates in the current visible dates then add recurrence appointment in AppointmentsSource if recursive dates in current visible dates. If RecurrenceRule added with no end date , then recurrence appointment should be added in the AppointmentsSource when all visible date changed from the recurrence start date. In the scheduler agenda view, the QueryAppointments command is used to load more appointments when the new month is loaded on view, whereas the new month appointments are added in scheduler AppointmentsSource. Other than agenda view, the scheduler AppointmentsSource can be reset for a new visible date range to improve appointment loading performance.

Examples

The following example describes to load appointments on demand using command

Event Type

Type
System.EventHandler<AppointmentDragStartingEventArgs>

Examples

The following code demonstrates, how to use the SfScheduler's appointment drag starting event.

Occurs after the tap interaction on Scheduler.

Declaration

public event EventHandler<SchedulerDoubleTappedEventArgs> DoubleTapped

Event Type

Type
System.EventHandler<SchedulerDoubleTappedEventArgs>

Examples

The following code demonstrates, how to use the SfScheduler's double tapped event.

this.Scheduler.DoubleTapped += this.OnSchedulerDoubleTapped;
private void OnSchedulerDoubleTapped(object sender, SchedulerDoubleTappedEventArgs e)
{
  var appointments = e.Appointments;
  var selectedDate = e.Date;
  var schedulerElement = e.Element;
}

LongPressed

Occurs after the tap interaction on Scheduler.

Declaration

public event EventHandler<SchedulerLongPressedEventArgs> LongPressed

Event Type

Type
System.EventHandler<SchedulerLongPressedEventArgs>

Examples

The following code demonstrates, how to use the SfScheduler's long pressed event.

Declaration

public event EventHandler<SchedulerQueryAppointmentsEventArgs> QueryAppointments

Event Type

Type
System.EventHandler<SchedulerQueryAppointmentsEventArgs>

Remarks

The SchedulerQueryAppointmentsEventArgs passed as command parameter. The QueryAppointments is used to load the appointments in on-demand for visible dates. Loading appointments in on-demand improves the loading performance when you have appointments ranging for multiple years. Once the ViewChanged event is raised, the QueryAppointments will be invoked. If an appointment has been added, deleted or updated within the visible dates, then the QueryAppointments will not be invoked. Since appointments were already loaded for that visible dates. The recurrence appointment should be added to the AppointmentsSource until the date of recurrence ends. If RecurrenceRule added with count or end date, you can use the GetDateTimeOccurrences(String, DateTime, Nullable<DateTime>, Nullable<DateTime>, Nullable<DateTime>, DayOfWeek) method to get recurrence date collection and compare recursive dates in the current visible dates then add recurrence appointment in AppointmentsSource if recursive dates in current visible dates. If RecurrenceRule added with no end date , then recurrence appointment should be added in the AppointmentsSource when all visible date changed from the recurrence start date. In the scheduler agenda view, the QueryAppointments event is used to load more appointments when the new month is loaded on view, whereas the new month appointments are added in scheduler AppointmentsSource. Other than agenda view, the scheduler AppointmentsSource can be reset for a new visible date range to improve appointment loading performance.

Examples

The following example describes to load appointments on demand using the QueryAppointments event.

this.scheduler.QueryAppointments += OnSchedulerQueryAppointments;
private async void OnSchedulerQueryAppointments(object sender, SchedulerQueryAppointmentsEventArgs e)
{
this.scheduler.ShowBusyIndicator = true;
await Task.Delay(1000);
this.scheduler.AppointmentsSource = this.GenerateSchedulerAppointments(e.VisibleDates);
this.scheduler.ShowBusyIndicator = false;
}
private ObservableCollection<SchedulerAppointment> GenerateSchedulerAppointments(List<DateTime> dateRange)
{
var appointment = new ObservableCollection<SchedulerAppointment>();
