Remarks

By default, end-users are allowed to copy appointments. Use the AllowAppointmentCopy property to control the availability of such functionality to end-users with regards to an appointment’s type. For instance, if the AllowAppointmentCopy property allows appointments of all types to be copied (the property is set to UsedAppointmentType.All), an end-user can copy the desired appointment by dragging it to a new time slot while holding down the Ctrl keyboard key (note that the SchedulerOptionsCustomization.AllowAppointmentDrag option should be enabled to allow dragging).

Note

If the AllowAppointmentCopy property is set to UsedAppointmentType.Custom, then whether an end-user is allowed to copy appointments or not is decided in the SchedulerControl.AllowAppointmentCopy event handler.

Example

This example demonstrates how to implement custom rules for editing and deleting appointments. The code below allows an appointment to be edited only by its owner (the end-user who created it). To do this it’s necessary to set the SchedulerOptionsCustomization.AllowAppointmentEdit and SchedulerOptionsCustomization.AllowAppointmentDelete properties to UsedAppointmentType.Custom, and handle the SchedulerControl.AllowAppointmentEdit and SchedulerControl.AllowAppointmentDelete events to implement custom logic for editing appointments.

using DevExpress.XtraScheduler;
// ...

private void schedulerControl1_AllowAppointmentDelete(object sender, 
    AppointmentOperationEventArgs e) {
   // Allow only the user who created this appontment to delete it.
   e.Allow = CanUserModifyThisAppointment(e.Appointment);
}
private void schedulerControl1_AllowAppointmentEdit(object sender, 
    AppointmentOperationEventArgs e) {
   // Allow only the user who created this appontment to modify it.
   e.Allow = CanUserModifyThisAppointment(e.Appointment);
}
// Determine if the current user is the same 
// as the one who created the specified appointment 
bool CanUserModifyThisAppointment(Appointment apt) {
   object obj = apt.CustomFields["Owner"];
   if (obj == null)
      return true;
   string appointmentOwner = obj.ToString();
   if (appointmentOwner == String.Empty)
      return true;
   return (String.Compare(appointmentOwner, tbUserName.Text, true) == 0);
}
