ASP.NET MVC adds Validation for non-required fields

I have a model class "Country" with property "CultureId" that is NOT marked as required. Another class "CountryViewModel" holds the same property "CultureId".

When rendering the "Create" view, I noticed that validation data attributes were added to the "CultureId" textbox, although there were no data annotations added.

I am using

@Html.HiddenFor(mode => mode.CultureId)

What might be the cause for such a behavior?

Thanks

There are couple of ways to handle this -
a). Make the property as Nullable like 

public int? Age  { get; set; }

b). Use the below in controller class - 

ModelState["Age"].Errors.Clear();

c). Add to the startup- DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

try this:

ModelState["CultureId"].Errors.Clear();

if (ModelState.IsValid)     
    {
         .....
    }

If CultureId is int then it will also give you the desired result...

I'm guessing your CultureId is an int. MVC automatically adds required tags to non-nullable value types.

To turn this off add 

DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

to Application_Start or make your int nullable

if you can use data annotations, you should check out this http://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.metadatatypeattribute.aspx

namespace MvcApplication1.Models
{
[MetadataType(typeof(MovieMetaData))]
public partial class Movie
{
}


public class MovieMetaData
{
    [Required]
    public object Title { get; set; }

    [Required]
    [StringLength(5)]
    public object Director { get; set; }


    [DisplayName("Date Released")]
    [Required]
    public object DateReleased { get; set; }
}

}

it helps you set validations without models on database side.
