There are lots of things that this could be used for, but thinking back to a previous thread, I had created a small example to show or hide an image button based on the value in a different column. That example was intended to hide a button once a user had a count of 50 it more in a column…so they couldn’t submit not than 50 times for example. Another example would be to only show a button to allow someone to proceed if they agreed to terms and conditions. It’s probably one of those features that won’t make much sense until you run into a situation where you actually need it.
