Hi Jean,
1. Synchronizing 2 or more scheduler control
As of now your requirement of synchronizing scroll viewer can be achieved using VisualTreeHelper by find the inner elements of the schedule control. We have prepared a sample for the same and please find the sample in the below link.
2. Drag and drop an appointment from one Scheduler control to another
As of now we are only having the support to drag and drop the appointment from list view to the schedule control and we don’t have any support to drag drop the appointment from one schedule control to other in same application. We have logged a feature request on this and this will be implemented in any of our upcoming release.
If the above provided solution or our definition of this feature is different from your requirement, then share the specific details with us—so that we can work towards fulfilling your requirements.
Regards
