Please use the js files from the packages, not the compressed versions from online samples. ( they have correct real names of methods , not the compressed abbreviations )

please let me know which js file

All files that you mentioned (dhtmlxGrid/codebase/dhtmlxgrid.js and others), but from the official PRO package.
