I see from the documentation that collision detection is not supported for recurring events. Is this on your product roadmap? It would be tremendously helpful!
In the event that it is not… Is there an event hook I could use if I felt adventuresome and wanted to attempt to detect collisions using my own logic?
Thanks,
Chris
So far we don’t plan to add the such functionality ( in case of events without end-date , its hardly possible to predict collisions )
You can alter collision_check method in dhtmlxscheduler_collision.js, logic in it check only first date of event for collisions. It possible to use getRecDates methods, to get all occurrences of event, and check them for collisions.
Hi,
I am using my own query to check for collisions onEventSave. When I use the getRecDates method in this function, it only returns the first date. When I have used the same logic in my onEventAdded function, it returns the correct set of dates. Am I missing something? Both functions are pasted below.

);change
scheduler.getRecDates(event_id)
to the
scheduler.getRecDates(event_object)
The problem is , in moment of onEventSave event is not change yet, so all API calls by ID will operate with event as it was before editing, while you need to get info about event how it will be after editing, which is second param of handler - event_obj
getRecDates can accept both event id, and event object as its parameter
