onEventCollision

fires when the user tries to create a new event (or modify some existing one) inside of some already occupied time slot

ev	object	the event object
evs	array	a collection of events' objects which already occupy the same time-slot

boolean

defines whether the default action of the event will be triggered (true) or canceled (false)

Example

scheduler.attachEvent("onEventCollision", function (ev, evs){
    //any custom logic here
    return true;
});

Returning true from the handler function blocks the event from being added/edited. Returning false - allows the collision, i.e. adding/editing events.
