The property ScrollX in the scheduler isn't updated when we set the date to scroll to.
It is only calculated on the first design time and never more recalculated, so on postbacks, SetScroll doenst work!
It seems to work fine with CallBacks - it's updated properly and it can be used to set a new position as well. I need to check if there is a problem with PostBacks. Is the PostBack invoked from within DayPilotScheduler (e.g. EventClickHandling = "PostBack") or from another control (like a Button)?
