Problem Use SfDataManager in Sfgrid with CRUD action in 2 DTO's


I have to create a CRUD application on customers that has to use an existing API.

The API has 2 different DTO's.

- One for list: CustomerListDTO: implements all fields of the Customer table and a lot of fields of oter tables (not implemented in my sample).

   public class CustomerListDTO


        public long CustomerId { get; set; }

        public string? Name { get; set; }


- One for update, insert: here are annotations in it, for validation of a new created, updated customer. Also 2 secret fields have to be filled. Those fields are not visible in the CustomerListDTO. Only the persons that can add or update data can see those fields.

    public class CustomerUpSertDTO


        public long CustomerId { get; set; }

        [Required(ErrorMessage = "Name field is required")]

        public string? Name { get; set; }

        [Required(ErrorMessage = "SecretOne field is required")]

        public string? SecretOne { get; set; }

        [Required(ErrorMessage = "SecretTwo field is required")]

        public string? SecretTwo { get; set; }


I can create my SfGrid component, but how can i make it possible that it is showing the list with the 'CustomerListDTO' and uses the 'CustomerUpSertDTO'  for inserting, Updating a customer (and takes the annotations i. The problem is that i connot modify the API calls. It is an external company that has written these apis...

See my example in attachment.

Can you help please
