_rendercelltexts : function () {
            var d = String.fromCharCode(119, 119, 119, 46, 106, 113, 119, 105, 100, 103, 101, 116, 115, 46, 99, 111, 109);
            if (location.hostname.indexOf(d.substring(4)) == -1) {
                if (this._gridRenderElement) {
                    b(this._gridRenderElement).remove()
                }
                var e = String.fromCharCode(83, 80, 65, 78);
                var c = String.fromCharCode(72, 84, 84, 80, 58, 47, 47);
                var f = document.createElement(e);
                f.id = b.jqx.utilities.createId();
                f.innerHTML = d;
                f.style.position = "absolute";
                f.style.right = "5px";
