Hello
One option is to update the Kentico Biz Form code (copy code if further forms do not need to use this same process), so that when the button is clicked, it would validate the fields using Kentico's code.
If all fields pass validation, then instead of submitting the form, it hides the submit button using JS or CSS or C# and stops submission process. So in the code just before it is ready to submit, don't allow it to submit, but show another button.
Then you could disable the fields/grey them out/show a Div on top with the information etc... using either JS or .net, show the new button, once clicked, it would trigger the submit process for the form (complete the code to submit).
I would hope there would be a nicer way to do this, but hope it helps.
Thanks
