Client-side custom data annotation validation

Question

I\'ve create a custom data annotation to do some validation on my view model. The problem is that it doesn\'t validate on the client-side. Here\'s my model:

Answer 1

Implementing Iclientvalidatable only adds unobtrusive attributes to generated html inputs. To enable validation on client side you must write validators that use these unobtrusive attributes to validate the inputs. Here you can find very good explanation of client and server validation in asp.net mvc 3

Answer 2

A Remote Validator is what you need here is the link http://www.devtrends.co.uk/blog/the-complete-guide-to-validation-in-asp.net-mvc-3-part-1

Answer 3

Had same issue recently. You can write:

$.validator.addMethod('enforcetrue', function (value, element) {
    return $(element).is(":checked");
});
$.validator.unobtrusive.adapters.add('enforcetrue', [], function (options) {
    options.messages['enforcetrue'] = options.message;
    options.rules['enforcetrue'] = options.params;
});
