There is no native support for such use-case, you can use js command ( lockItem ) instead of attribute and place all necessary logic in js code.
As i dont have a pro edition cant you please send me the file... it would be of great help for me  ... Just send me the trial file which could provide this facility.. please

You can request a fully functional evaluation version of pro edition - please contact sales@dhtmlx.com with such request.
