As I said, I've built a custom datagrid, so I can't use the regular 
datagrid commands.
Before each query, all the fields are emptied, and then, depending on 
the number of
results of the query, only one row (6 fields) can be filled, or up to 
1800 rows
(10800 fields).
Emptying the fields and then inserting new contents is pretty fast, even 
for sucessive
queries on the same card. The only problem is the delay when going to 
the next card.
I might be wrong, but I have the impression that the engine is storing 
the content of
the card somewhere before switching to the next card, for faster display 
when returning
to the first card.
I am using LC Community 9.6.2 on Mac OS Cataline 10.15.8.

Best,
