[SOLVED] DataGrid and ChangingHistory topics

Dear Mr babyrus, i cleaned the IE catche and just test the program for 10 times. I observed to changes in data grid date format. May i ask you to test my code your self? May be there is a little mistake i can not find out. I just attached my edited projeqtorFormatter.js file which must be placed in view/js. I tested the source code more than 10 times in my sample files, but when i put it in the software directoty, it does not work. I am just confused ! As Kunena does not allow js type attachment i just zipped the file and attached it. Thanks for your help !

Yes, Thank you. Then i will try to work on it more to solve my question. Would you help me on following questions:
1- Where is this formatDate (date) used in codes? would you tell me where it is used for the datagrids?
Thank you very much
