Yes, but the button in the tutorial shows filters/does a requery. It doesn't put the dataset in editmode.
Once again, AFAIU, the grid should handle this itself.
Anyway, was just setting up the tutorial with SQLite3 and the attached worked for me without modification (other than changing the TIBConnection for the SQLite equivalent)...
(Note: you'll need an sqlite3.dll there or in your PATH/Windows/system32 directory)
