You can change the behavior for getLength in client validation to double count newlines by adding the following to your javascript after you've included jquery.validate.js. This will cause the server-side and client-side length methods to match letting you use the StringLength attribute (I assume your issue with StringLength was that the server and client validation methods differed).

$.validator.prototype._getLength = $.validator.prototype.getLength;
$.validator.prototype.getLength = function (value, element) {
// Double count newlines in a textarea because they'll be turned into \r\n by the server. 
    if (element.nodeName.toLowerCase() === 'textarea')
        return value.length + value.split('\n').length - 1;
    return this._getLength(value, element);
};
