If anyone has a tutorial or sample code for this it would be greatly
appreciated! This issues comes up from time to time and there is not a
lot sample code out there for it. Most of the posts are conceptual
rather than examples.

after changing one (or a few) values.
Informative, thank you.
Yup, Scott's idea sounds like a good plan. Most people get good
performance out of variable row heights by doing some sort of
caching or heuristic that quickly determines the row height.
