Event for Appointment created?

[Anastasios]

Does an event who fires when an Appointment is created  exists? For example, when the Appointment Factory creates an appointment based in Database data.
My purpose is to calculate dynamical the start date of an appointment based on the end date.

Hello Anastasios,

Thank you for writing.

You could subscribe for the CollectionChanged event of the Appointments collection of the scheduler:
 

this.radScheduler1.Appointments.CollectionChanged += new Telerik.WinControls.Data.NotifyCollectionChangedEventHandler(Appointments_CollectionChanged);

 
In this event you could check the action state and if it is an Add state do the changes that you want:
 

void Appointments_CollectionChanged(object sender, Telerik.WinControls.Data.NotifyCollectionChangedEventArgs e)

{

    if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.Add)

    {
           //Add your code here

    }

}

If you have additional questions feel free to contact us.

Sincerely yours,

Thank you very much again Dobry.

But  I cant get it to work.I have used the code you provided but it seems that the event doesn't fire.
My scheduler is data bonded.Normally the event should fire when the scheduler creates the appointments from the database,right?

Hello Anastasios,

Thank you getting back.

This event is fired when the appointments collection of the scheduler is changed. Could you provide more details on your scenario in order to give you best way to implement it? Feel free to open a new support ticket and send us your project as well - this will be the best way to proceed and will take the least amount of time to find where the problem is.

Kind regards,

The scenario I have in mind is the following:
Consider that my appointment datatable has not any Start date field.Only End date field and a Timespan field.
I want  the start date to be calculated on the fly (on scheduler load/data bind maybe is more accurate)  based on the End date. Actually like this Start Date = ( End date - Timespan).

Hello Anastasios,

RadScheduler does not support this functionality out-of-the-box, however you can calculate the start date/time on the fly in the DataSet based on the End date and duration. Once the start date/time is determined, you can pass it to the Scheduler, together with the end date, and the appointment will show fine with the appropriate time span.

Note that the start and end dates are the most important fields for the scheduler and you cannot show an appointment where the start date is null.

Thank you again for your excellent help Dobry.

I found a workaround by executing this custom function on Form load:

private void setAppointmentsDate_scheduler()
        {
            if (scheduler.Appointments.Count > 0)
                  foreach (QuickTask task in scheduler.Appointments)
                     {
                          DateTime startDate = task.OurDeadline;
                          TimeSpan hours = new TimeSpan(Convert.ToInt32(task.TimeEstimation), 0, 0);
                            startDate = startDate.Subtract(hours);
                            task.Start = startDate;
                       }
        }

 Where QuickTask is my custom Appointment class and the start Date is calculated from the OurDeadline - TimeEstimation.
Could you please provide me some more information about calculating Date start on the fly in the Dataset? Its sounds interesting :)

Thank you again
