Hello Dan,
Unfortunately there isn't. Dynamic Forms is a hefty piece of code that you can't simply paste ASP.Net code into it and render a form.
Dynamic Forms is not a form itself. It's a form building tool, there's a big difference
That is a very interesting idea that could be an enhancement request for the future. But the code to allow something like this would be cumbersome to implement alongside with Dynamic Forms original capabilities.
Let me know if you have any questions.
Thanks,
Ryan
