Hi Jurgen,
Your requirement can be achieved with the help
of LoadOnDemand Command in SfScheduler. Inside the LoadOnDemand command, you
can filter the appointments with the help of visible dates of the view and set the collection to display in the view. Please refer to the code snippet for
your reference.
Code snippet
|
public async void
ExecuteOnDemandLoading(object parameter)
{
if (parameter == null)
{
return;
}
this.ShowBusyIndicator = true;
await Task.Delay(500);
await Application.Current.MainWindow.Dispatcher.BeginInvoke(DispatcherPriority.ApplicationIdle,
new Action(() =>
{
this.Events = this.GenerateSchedulerAppointments((parameter
as QueryAppointmentsEventArgs).VisibleDateRange);
}));
this.ShowBusyIndicator = false;
}
/// <summary>
/// Method to generate scheduler appointments based on
current visible date range.
/// </summary>
/// <param name="dateRange">Current visible date range.</param>
private IEnumerable GenerateSchedulerAppointments(DateRange
dateRange)
{
var appointments = new
ObservableCollection<SchedulerModel>();
foreach (SchedulerModel app in
ActualEvents)
{
if
((app.From.Date >= dateRange.ActualStartDate.Date && app.From.Date
<= dateRange.ActualEndDate.Date) ||
(app.To.Date >= dateRange.ActualStartDate.Date &&
app.To.Date <= dateRange.ActualEndDate.Date))
appointments.Add(app);
}
return appointments;
}
