Why don't you just put two buttons labeled next and previous, then
simply change the label text values and textField values when they are
pressed. You can keep 3 or 4 textfields depending on your program.
And if any textfields are left over in the last bunch of datavalues then
just make them invisible.
Further suggestions if helpful:
If the order and number of textfields aren't obvious, put more labels
with numbers in them, and write out the total number of textfields below
in another label.
If you want the original scrolling effect then place these where the
scrollbar is and make a bar the same color as the scrollba with a
seemingly moving bar via drawing rects, although this would be too much
work and ridiculous in my opinion.
