Conflict on form validation Server/Client about decimal separator

Question

My model:

    [Required(ErrorMessage = "Required field")]
    [Display(Name = "Price")]
    public decimal Price { get; set; }

My view: There is a form with several other input fields and an input field for Price

@Html.EditorFor(model => model.Price, new { htmlAttributes = new { @class = "form-control"} })

Issue:

• [Browser validation] If I insert 2.3 on input field I get "Field needs to be a number"
• [Server Validation] If I insert 2,3 on input field it does not give any error immediately but after submitting the form I get "value not valid"

What I've tried: There is a lot of topics about this on SO so I've tried several suggestions but unfortunately without success.

• Suggestion A - System.Globalization.CultureInfo.DefaultThreadCurrentCulture = new System.Globalization.CultureInfo("pt-PT"); in Application_Start()

• Suggestion B - put <globalization uiCulture="pt-PT" culture="pt-PT" /> in web.config

• Suggestion C - (in despair) data_val = "false" in input field to disable browser validation. When I did this I found two things: if I input 2.3 a value of 0 reaches the controller; if I input 2,3 a value of "2.3" (with the point) reaches the controller but after saved to the DB is loses the decimal part, I mean only "2" is saved on the DB table

• Suggestion D - Even if I force a number with comma on the code, when I inspect it in debugging mode, I see it is using a dot and when stored in BD it only stores "2". How can that be possible?

  Ingredient ingredientToAdd = new Ingredient { Name = ingredient.Name, Price = Decimal.Parse("2,3"), VAT = ingredient.VAT };

      if (ModelState.IsValid)
      {
          db.Ingredients.Add(ingredientToAdd);
          db.SaveChanges();
          return RedirectToAction("Index");
      }
