SchedulerView AppointmentSaving event goes infinite

[palak]

dear telerik team,

Here is a strange problem i am facing with appointmentsaving event of scheduleview. It loops infinite with the fact that i've not added any loop in my code. kindly see below code. Another fact is, below code perfectly works with RadScheduler Control, but not working with Radscheduleview.

private void SchedulerView_AppointmentSaving(object sender, AppointmentSavingEventArgs e)
       {
           busyIndicator.IsBusy = true;
           _ResourceAppointment = _Context.Web.Lists.GetByTitle("Events2011");
           _ResourceAppointmentList = new List<ResourceAppointment>();
           SP.ListItem listItem = _ResourceAppointment.AddItem(new ListItemCreationInformation());
           ResourceAppointment newAppointment = e.Appointment as ResourceAppointment;
           listItem["Title"] = newAppointment.Subject.ToString();
           listItem["EventDate"] = Convert.ToDateTime(newAppointment.Start).ToLocalTime();
           listItem["EndDate"] = Convert.ToDateTime(newAppointment.End).ToLocalTime();
           listItem["Description"] = newAppointment.Body.ToString();              listItem.Update();
           _ResourceAppointmentList.Add(newAppointment);
           SchedulerView.AppointmentsSource = _ResourceAppointmentList;
           _Context.Load(_ResourceAppointment, list => list.Title);
           _Context.ExecuteQueryAsync(OnSaveItemToListSucceeded, OnSaveItemToListFailed);
       }

kindly respond whats wrong with this.

thanks

Guys,

Have you got anything regarding this issue ?

[palak]

guys,

can u pls respond at least, whats wrong going with my code ?

this is the statement from where control bounces back to first statement of my appointmentsaving event, if i remove this, working fine. but i need to use this statement as i want to assign appointments list source to scheduleview appointment source to update it.

SchedulerView.AppointmentsSource = _ResourceAppointmentList;

kindly suggest, because my code is working perfectly with Scheduler control, but not with ScheduleView.

thanks & regards

Hi Palak,

This is expected behavior - It is not recommended to change the AppointmentsSource of the ScheduleView in AppointmentSaving event handler. Please explain in more details your scenario so we to be able to provide a suitable solution.

I am running in same problem infinite loop occuring on AppointmentSaving event when trying to change AppointmentSource in AppointmentSaving event handler. If this is not recommended what is the right way to change AppointmentSource. After saving an appointment to database which event handler should be used to update source of ScheduleView?

Palak, How did you manage by alternate way?

satyendra,

i rebind the scheduler by calling my private method. you can call your method after any CRUD operations which specifically bind scheduler with the latest appointments as per your database.
 
But yes, i would say, appointmentsource property should not be set in any event of scheduler as per telerik.
