[@foxlearn]

You're welcome. Thank you !

Excellent video like always. I have a question, though. How do I prevent the validator to enter 0s in my form when initiated? I'd like it to have empty fields instead of 0s.

[@alipio20233]

Muito Bom! Parabéns.

[@foxlearn]

Muito obrigado

[@zyrpentq1395]

is there a way to implement this on an existing form without having to remake it. i already have a functioning form but the controls arent bound to a class but i want to implement validation using the annotation used in the video

[@danryox1]

What can I add to tell the user the form is saved successfully?

[@adilsiddique92]

for me model class is not showing under data object inside data sources, can you help.

[@atpayero]

Excellent video, it is important that you increase the size of the text in the videos a bit.
