scheduler refresh after editing appointment

[the carpenter]

Hi,

In my project, I use sfscheduler control with custom scheduler Editor.

After editing it (end time for example), I save modifications in the appointment, but the appointment not resizing.

However, if I edit the appointment, the end time has been modified.

How can I refresh the scheduler?

Thanks

Jim

Hi,

Thank you for your answer.

When I add my appointment to the appointment collection, it appears on the scheduler, but I don't know how to update an existing appointment?

Thanks

Hi Jim,

To update an existing appointment when opening the editor, you can access the appointment using the AppointmentEditorOpening event. After making the necessary changes, the updated values can be saved back to the existing appointment when the save button is clicked. Below is an example of how to implement this:

public partial class AppointmentEditor : Window

{

    private SfScheduler scheduler;

    private ScheduleAppointment appointment;

    public AppointmentEditor(SfScheduler scheduler, ScheduleAppointment appointment, DateTime dateTime)

    {

        this.scheduler = scheduler;

        this.appointment = appointment;

    }

    private void OnSaveClicked(object sender, RoutedEventArgs e)

    {

        if (appointment == null)

        {

            var scheduleAppointment = new ScheduleAppointment();

            scheduleAppointment.Subject = this.Subject.Text;

            scheduleAppointment.StartTime = this.StartDatePicker.Value.Value.Date.Add(this.StartTimePicker.Value.Value.TimeOfDay);

            scheduleAppointment.EndTime = this.EndDatePicker.Value.Value.Date.Add(this.EndTimePicker.Value.Value.TimeOfDay);

            scheduleAppointment.Location = this.location.Text;

            scheduleAppointment.IsAllDay = (bool)this.allDay.IsChecked;

            scheduleAppointment.Notes = this.description.Text;

            scheduleAppointment.Reminders = (ObservableCollection<SchedulerReminder>)this.ReminderList.ItemsSource;

            if ((bool)this.timeZone.IsChecked)

            {

                scheduleAppointment.StartTimeZone = this.TimeZoneMenu.Text;

                scheduleAppointment.EndTimeZone = this.TimeZoneMenu.Text;

            }

            if (this.scheduler.ItemsSource == null)

            {

                this.scheduler.ItemsSource = new ScheduleAppointmentCollection();

            }

            (this.scheduler.ItemsSource as ScheduleAppointmentCollection).Add(scheduleAppointment);

        }

        else

        {

            appointment.Subject = this.Subject.Text;

            appointment.StartTime = this.StartDatePicker.Value.Value.Date.Add(this.StartTimePicker.Value.Value.TimeOfDay);

            appointment.EndTime = this.EndDatePicker.Value.Value.Date.Add(this.EndTimePicker.Value.Value.TimeOfDay);

            appointment.Location = this.location.Text;

            appointment.IsAllDay = (bool)this.allDay.IsChecked;

            appointment.Notes = this.description.Text;

            appointment.Reminders = (ObservableCollection<SchedulerReminder>)this.ReminderList.ItemsSource;

            appointment.StartTimeZone = this.TimeZoneMenu.Text;

            appointment.EndTimeZone = this.TimeZoneMenu.Text;

        }

        this.Close();

    }

}

Hi,

I don't know why it doesn't work.

If I use ScheduleAppointment class, it works very well. I can change StartTime property and the appointment resizing automatically

If I use my custom class , after saving, the appointment not resizing.

Here is my Custom Appointment class:

using Syncfusion.UI.Xaml.Scheduler;

using System.ComponentModel;
using System.Windows.Media;


namespace WpfApp1
{
    public class Appointment : ScheduleAppointment, INotifyPropertyChanged
    {


        private String _name;
        public String Name
        {
         get { return _name; }
         set
         {
         _name = value;
         OnPropertyChanged("Name");
         }
        }


       public new event PropertyChangedEventHandler PropertyChanged;
        public void OnPropertyChanged(string propertyName)
        {
         var eventHandler = this.PropertyChanged;
         if (eventHandler != null)
         {
         eventHandler(this, new PropertyChangedEventArgs(propertyName));
         }
        }
    }
}

In my main window  : 

            Appointments = new ScheduleAppointmentCollection();
            for (int a = 0; a <= 10; a++)
            {
                var newApp= new Appointment() //If I use ScheduleAppointment, it works fine !
                {
                    Subject = "Subject " + a,
                    Name = "Name " + a,
                    StartTime = Convert.ToDateTime(plann.Rows[a]["datedebut"].ToString()),
                    EndTime = Convert.ToDateTime(plann.Rows[a]["datefin"].ToString()),
                    ResourceIdCollection = new ObservableCollection<object>() {a}
                };
                Appointments.Add(newApp);
            }
            Schedule.ItemsSource = Appointments;

Hi Jim,

Regarding issue Appointment fails to resize when using custom appointment inherited from ScheduleAppointment.

We have fixed the reported issue and included the issue fix in our latest weekly NuGet release update version 28.2.5, which is available for download at nuget.org

Root cause: The issue occurred because the custom appointment, inherited from ScheduleAppointment, is being treated as a custom appointment rather than as a ScheduleAppointment.

We thank you for your support and appreciate your patience in waiting for this release. Please get in touch with us if you require any further assistance.

Hi,

Thank you for this release. Effectively, this release fixed the bug, and now, I can change the custom property "name" from my customAppointment and it appears in the scheduler.

But, If I change starTime or endTime (inherits from SchedulerAppointment), for example, the time is saved in the collection, but the meting is not resized 

        private void Schedule_AppointmentTapped(object sender, AppointmentTappedArgs e)
        {
            CustomAppointment ca = (CustomAppointment)e.Appointment;
            ca.EndTime = ca.EndTime.AddMinutes(-15); //saved, but no changes on Scheduler
        }

Hi Jim,

Regarding issue Appointment fails to resize when using custom appointment inherited from ScheduleAppointment.

Based on our review, we noticed that you have created a new PropertyChanged event of type PropertyChangedEventHandler in the custom appointment class, which prevents the Scheduler's base PropertyChanged event from being triggered.

To resolve this, we recommend using the Scheduler's RaisePropertyChanged method directly and passing the property name as a parameter, as demonstrated below.

private String _name;

 public String Name

 {

     get { return _name; }

     set

     {

         _name = value;

         base.RaisePropertyChanged(nameof(Name));

     }

 }

We have prepared a simple sample demonstrating this. Please check the attached sample for your reference.

If you have any further questions or require assistance with any other aspect, please don't hesitate to let us know. We are here to help.
