Hi Håkan,
I am sorry, but the ScheduleView doesn't provide a way to check which group is visible at the moment. If it is before the first visible group, I can suggest you to use the
FirstVisibleGroup property of the ScheduleView. But for the ones after the end of the visible range there is no public accessible information for the groups.
Sorry for the inconvenience.
Kind regards,
Konstantina
