Check value before inserting new user

Radzen Studio Angular
1

Hello.

I'm testing Radzen and I'm thinking to buy it.
I setted up all the CRUD pages for users table. My table has a id_user that is unique for each user.
How can I give this number automaticaly on radzen and make the validation if username exists.

kind regards

Maybe you could create a partial class for the generated controller and perform the validation there. We have some examples here.
