The way I would have done it in the first place is to maintain a current
version in a local variable to the data module or form. Then, in the
OnDataChange event I would compare the current value in the data with the
current stored value. If there is a difference then you have your culprit.

You would just have to tell the difference between a record being scrolled
or an actual change. This should be as simple as whether the dataset is in
an edit state or not.
