Easy UI Combobox顯示拼接欄位

 $('#MaterialID').combobox({
                url: '../ashx/MD/MDMaterialHandler.ashx?action=select&&option=null',
                valueField: 'MaterialID',
                textField: 'MaterialDes',
                formatter: function (row) {
                    return row.MaterialDes + "(" + row.MaterialID + ")";
                },
                panelHeight: 200,
                editable: false
              

主要是formatter來控制
