WPF RadScheduleView Managing Recurrence Appointments from the server side

[Ohad]

I use RadScheduleView for appointments for users who need to get them on mobile.

I mean I have a desktop app where someone manages the schedule and appointments and he sends them to the server

and saves them in DB.

The server should then send the appointments to the user accordingly.

The question is what should I do if I have an appointment created let's say two years ago and it recurrence which means

it still comes back every week and the server needs to find it to send to the user.

How can this be dealt with?

Because in normal cases the server can do a search for appointments created on dates from X to Y,

but in this situation, it will not see this appointment.

Would appreciate help.
