Thank you for your reply our mail.
(1)I can read the existing records now, when I write the new record in the existing cell , but I saw the database don’t change. I use the mssql server and mysql server.
I used your example “savedata_grid.html” as same time.
Beware that dataprocessor ( used in mentioned sample ) will not react on cell changes triggered by API calls, it will react only on edit operations initiated by user actions.
If you need to update cell by API, you can force server update manually.
dataproc.setUpdated(id,true); //force data saving
