I am trying to make a validator that will make sure that at least 2 items are selected. The validator works correctly on the server side but the client side code never gets executed.
Here is the code:
Sys.Mvc.ValidatorRegistry.validators["country"] = function (rule) {
var min = rule.ValidationParameters["min"];
return function (value, context) {
if (value >= min) return true;
return rule.ErrorMessage;
};
};
And here is the validator code:
public class CountryValidator : DataAnnotationsModelValidator<CustomValidations.CountryAttribute>
{
private int _minimum;
private string _message;
public CountryValidator(ModelMetadata metadata, ControllerContext context, CustomValidations.CountryAttribute attribute) : base(metadata,context,attribute)
{
_minimum = attribute.Minimum;
_message = attribute.ErrorMessage;
}
public override IEnumerable<ModelClientValidationRule> GetClientValidationRules()
{
var rule = new ModelClientValidationRule()
{
ErrorMessage = _message,
ValidationType = "country"
};
rule.ValidationParameters.Add("min", _minimum);
return new[] { rule };
}
}
I have even registered the validation adapter in global.asax file:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(AgeAttribute), typeof(AgeValidator));
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(CountryAttribute),typeof(CountryValidator));
}
I am thinking that the validator only works with the elements that have a value property like textboxes etc.
UPDATE 1:
EnableClientValidation is invoked correctly and all the required JS files are included in the project. It seems like I need to attach the onblur to the context. I will try that and post the results.
