I am not sure that I understand what you mean about "lose the
changes". How are you losing changes?

If you want to prevent posts when the row is not changed, you need to
check the Modified property of the dataset. You may be able to
achieve what you want in the BeforeScroll event, by checking if
the dataset is Modified and calling Post or Cancel as required.
