Yes we do, and I suspect we wont get far continuing that line
of thought.

I disagree with the "must", but this is obviously for Jason
to decide.

Obvious and easy dont always equate to best. Embedding code that
changes the state of related datasets into a dataset event is very
often a bad idea. Whether the Scroll events are changed or not I
still think you would be best served by externalising this code.

If the change to user interface that I suggested is not appropriate
then I suggest interacting with the Grid (the probably OnClickCell
event) to detect the changes before they get into dataset events.
