recognizing DataArrived events originating from paging

When scrolling a ListGrid with a large dataset, the data is loaded as I go. This causes new fetch operations, and new DataArrived events to happen continuously.

Is there a way to recognize/detect these DataArrived events?
(I mean, to tell them apart from events caused by other reasons, like data modification.)

Either a notification beforehand or a way to detect that this is happening would be fine.

I am still interested in this.
