One was to tell is in the events after the drop has finished...

private void ultraDayView1_AppointmentsDragDrop(object sender, AppointmentsDragDropEventArgs e)

{

if (e.HasCopies)//we are copying by using the cntl key

{

}

else //we are dragging, so need to actually move appts

{

}

}

Well, that would work I suppose, and if that is the only option, I will go with it. Ultimately I need to know that an appointment was either moved or copied and I would hope that there would be some event fired (or some indication on the AppointmentsDragDrop event that tells me it is moved or copied).

Perhaps I am missing something more basic.  Here's more background. I am storing my appointments in multiple backend systems, and I had a custom class and went down that road of databinding, but  to databind properly I need the recurrence object and the appointment object built into my custom class, so that seems a bit pointless so I'm just using the AppointmentsCollection as my main data. In addition, dataninding doesn't address the issue of how to know something was added/changed/deleted. I would rather not keep a copy of the entire appoitment class and then compare the 2 when anything changes to see what was changed/added/deleted.  So, perhaps there's a better event to trap.  I am trapping the validateAppointments to deal with the Save button on the UI, and that all works fine.  It would be nice if behind the scenes the draganddrop fired an appointment changed event(or even an appointment added and appointment deleted event) and a ctrl - drag fired just an appointment added event, and maybe there is something that does that that I am unaware of.

So, are there a combinaton of events that will cover an appointment being added, updated, or deleted that will work with draging and dropping; is there anyway to know on the dragdrop event that it was a copy and not a move; or am I stuck with trapping keydowns?

Thanks!
