That's right, not only must the interface must be separated from
the implementation (which is not the case with IBO) but the
application should adhere to the MVC model where the Control of data
is separated from the View. However, as I told Geoff, this is a
problem which happens regardless of how the dataset is scrolled...
whether its from a grid, or a NavBar, or a Cancel, etc.
In fact, I have determined that I just can't use the Scroll events
at all for what I need to do. So I just have to keep all datasets
open for the duration of the user session as opposed to intelligently
open/closing them depending on where the user tramples on my form.
C'est la vie...
