Here is a solution to your problem, easy and straight forward. But its going bit around, eg not using the build in MVC wrapper which should do it for you.

Reality is (at least it sounds like) this functionality is not supported out of the box at the moment, which is quite a surprise.

Here is a whole thread talking about this issue, with recommended solution :

(function ($, kendo) {
    $.extend(true, kendo.ui.validator, {
        rules: {
            mvcrequired: function (input) {            
                if (input.filter("[data-val-required]").length) {
                    var value = input.val();
                    return !(value === "" || !value);
                }
                return true;
            }
        },
        messages: { 
            mvcrequired: function (input) {
                return input.attr("data-val-required");
            }
        }
    });
})(jQuery, kendo);

I am sure you had a look here .
