Your guess is good, TempListe is a cursor created via a SELECT-SQL. I did insert the code to blank the RecordSource of the grid and all the ControlSource of the columns before the SELECT, with no result.

Note that basically the same code run fine before the SELECT, but not after.

TIA

>I guess that TempListe is a cursor and there is some precaution you may take in this situation: any time you rebuild the cursor running SELECT, disconnect grid from cursor before SELECT by setting RecordSource="". For some reason grids don't like to be bothered too much from Activate events.
