Form with math calculated values

I have a Form with 3 text fields (A,B,C).
I need that changing Field A or B, C=A*B in real time.
I see an easy and well constructed way in datatable but I don’t know if there is a easy way to do in a a form as well.

Thanks

Using text control/counter, you need to use the available API: change events and get/setValue methods.

Ok!
Very Clear!
Thanks!
