required field - validation doesn't display in bootstrap modal popup MVC

Question

I want to add product in my website. When I click create a product I must enter some value. When trying to save without any data, you want to check that validation work. It work, but when I click submit the form is not in modal popup (image2) - it display like other site

I want to like this (image1) - display in modal popup

Validation highlighted in red is Polish but it means that the fields are required.

I use formData because I must send a file.

modalform.js

var formdata = new FormData($('form').get(0));
    $('form', dialog).submit(function () {
        $.ajax({
            url: this.action,
            type: this.method,
            data: formdata,
            success: function (result) {
                if (result.success) {
                    $('#myModal').modal('hide');
                } else {
                    $('#myModalContent').html(result);
                    bindForm();
                }
            }
        });
        return false;
    });

I'm using AJAX posting to submit the data from my form. When using $(this).serialize() the ajax success is being called but the file is not returning as the content type is different. How can I change this??

Add the validations in the model class

public partial class Produkty
    {
        [Required(ErrorMessage = "*")]

        public int PRO_Id { get; set; }
        [Required(ErrorMessage = "*")]

        public string PRO_Nazwa { get; set; }
        public string PRO_Jednostka { get; set; }
        public float PRO_Vat { get; set; }
        public string PRO_Rodzaj { get; set; }
        public string PRO_Opis { get; set; }
        public string PRO_Waluta { get; set; }
        public float PRO_CenaN { get; set; }
        public float PRO_CenaB { get; set; }
        public string PRO_ZdjecieN { get; set; }
        public byte[] PRO_ZdjecieF { get; set; }
    }

Add this code in your view page

   $('#form1').removeData('validator');
   $('#form1').removeData('unobtrusiveValidation');
   $.validator.unobtrusive.parse('#form1');
