Scheduling AppointmentForm

Hello,
I'm trying to build my own Appointment Form with specifics components and, may be could you enlight me about the AppointmentForm Class.
In the AdvancedItemDrawing sample, the code to update an appointment is clear and pretty short:
Code
Select All
private void calendar_ItemClick(object sender, ItemMouseEventArgs e)
{
    if (e.Clicks == 2 && e.Button == MouseButtons.Left)
    {
	calendar.ResetDrag();
	AppointmentForm form = new AppointmentForm(calendar.Schedule);
	form.SetAppointment(e.Item as Appointment);
	form.ShowDialog(this);
    }
}
 


... but it's kind of a magic! How the modifications done in the dialog form are stored and update the clicked appointment? And, by the way, how could I update an existing appointment?
Kind regards

Hi,

The changes to the item (specified by AppointmentForm.SetAppointment) are automatically applied by the form when the user clicks the 'Save and Close' button. The form traverses all controls and sets their values to the respective item properties. For example, the TextBox containing the header text of the item is called _tbSubject. When the user saves the changes, the form does something like this:

Code
Select All
if (app.Subject != _tbSubject.Text)
	app.Subject = _tbSubject.Text; 


Where app is the edited appointment.

Regards,
Meppy
