Hi!

Do you restore data session back after checking? In other words, does your code looks like following:

nOldDataSession = SET("DATASESSION")
... do something in the default data session
SET DATASESSION TO (nOldDataSession)

Wneh above do not help, then re-open the tabel in private data session.

When grid cannot reach its record source, it is reconstruted (see VFP Grids article in the August issue of UT Magazine).

HTH.
