how to know edit series button clicked onLightBox

Hi

how to know edit series button clicked or edit ocuirrance, onLightBox event in scheduler.

There is no way to obtain such info. On moment of onLightBox event, info about real action that triggered lightbox is already lost.

On other hand, you can check id of event, if it contains “#” symbol - this is instance of event, in other case this is series.
