    if( $.SmartForm.ResponseContext.ActivityCode == "Activity2" ) {
            // 添加一行子表空白行
            var controlManager = that.D150516Addthemerchants;//获取子表控件对象
            var controlManager1 = that.D150516shoppingList;
            controlManager1.ClearRows();//清除子表行
            var subObjectId = $.IGuid();  //创建行ID
            controlManager.AddRow( subObjectId, {
                "D150516Addthemerchants.names": ""
            })
