Add custom messages to Validation Summary in asp.net mvc form

Sometimes you might need to add messages to Validation summary. Here is a small javascript function that will help you do that. The method can be called onClick event of a button.

    function performValidation() {
        if ($("#notestext").val() == "") {
            var ul = $("#validationSummary ul");
            ul.html("");
            ul.append("<li>" + "Action Note must be entered." + "</li>");
            return false;
        }
        return true;
    }

Hope it helps
