Hi Amf,
Thank you for contacting us.
This appears to be an issue in the drag&drop functionality of
RadScheduler. It has already been reported by another client and we are currently working on it. Most probably, it will be addressed in the next official release. Here is the
PITS item I have created about the previously reported issue. It concerns the
DataItem property, but the reason which is causing it is that the
e.Appointment is actually a different object, which is your case. You can subscribe to this PITS item to track its progress.
Meanwhile, I can suggest the following workaround which uses reflection to get the original appointment:
Do not hesitate to write back if you have any further questions.
