ASP.NET MVC 3 unobtrusive validation and radio buttons

Question

I\'m trying to do required validation on a list of radio buttons to force the user to select an option to continue. The validation does work but it only outputs metadata on

Answer 1

This can be performed by using the showErrors callback:

$("form").data("validator").settings.showErrors = function (errorMap, errorList) {
    this.defaultShowErrors();

    $("input[type=radio][data-val=true].input-validation-error").each(function () {
        $("input[name=" + $(this).attr('name') + "]").addClass("input-validation-error");
    });

    $("input[type=radio][data-val=true]:not(.input-validation-error)").each(function () {
        $("input[name=" + $(this).attr('name') + "]").removeClass("input-validation-error");
    });
};
