Why Range Data Annotation is not working on checkbox in client side?

Anonymous User 3329 18-Aug-2014

I have a form with some fields with the Required Data Annotation and then i have a "Accept Terms and Conditions" checkbox with the Data Annotation [Range(typeof(bool), "true", "true", ErrorMessage="You must accept Terms And Conditions to proceed")] Everything works fine but the thing that is annoying is that the Required Data Annotation fires the errors before post.. i mean, i click on submit and the form does not make a post and it shows the errors but with the Range, the form post and then shows the errors.

Why is that? is that a common behavior?

Hi Chintoo,
public class EnforceTrueAttribute : ValidationAttribute, IClientValidatable
    {
        public override bool IsValid(object value)
        {
            if (value == null) return false;
            if (value.GetType() != typeof(bool)) throw new InvalidOperationException("can
only be used on boolean properties.");
            return (bool)value == true;
        }
        public override string FormatErrorMessage(string name)
        {
            return "The " + name + " field must be checked in order to continue.";
        }
        public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata
metadata, ControllerContext context)
        {
            yield return new ModelClientValidationRule
            {
               
ErrorMessage = String.IsNullOrEmpty(ErrorMessage) ?
FormatErrorMessage(metadata.DisplayName) : ErrorMessage,
               
ValidationType = "enforcetrue"
            };
        }
    }

And in my JS:

jQuery.validator.addMethod("enforcetrue", function (value, element, param) {
            return
element.checked;
        });
       
jQuery.validator.unobtrusive.adapters.addBool("enforcetrue");
