I am working on a Styles dialog for Koda. It (and those for other controls) accept that not every combination of styles works -- even those that MSDN is silent on! So, as well as offering the user to opportunity to try any styles he likes, it has Presets: combinations that are known to work and are fairly commonly used. The dialog also shows a sample of how the control will look and behave with each combination of styles. For almost all other controls, the dialogs have been written and tested.
