.NET 4 MVC 2 Validation with annotations warning instead of error

Question

I am using .NET 4 with MVC 2 for validating with Annotations. Is there a (simple) solution for giving back a warning instead of the error?

Answer 1

All validation Attributes have ErrorMessage property. You can give your custom error message

public class Product
{

    [StringLength(50)]
    [Required(ErrorMessage = "Your user friendly message")]
    public string Name { get; set; }

}

Then change the CSS styles of the error messages.

/* Styles for validation helpers
-----------------------------------------------------------*/
.field-validation-error
{
    color: #ff0000;/*change the color*/
}

/*Other validation related styles*/
