Hi Abu
I noted that, investigating with a debug, in a my grid that has more subgrids the select_command of the subgrid is executed until 4 times, slowing much execution time.
There is a motif that i don't know?
How can I do?
Suggestions?
Thanks in advance

Hi,
Each grid is loaded using 3 select calls.
First query is executed when grid structure is form. Query returns the column meta data. It is run once query.
For each data request, 2 select queries are executed. One for total count of records, and one for paginated data.
If using subgrid, same applies for each grid display and this cannot be reduced according to our dev team.
What i suggest now is to monitor the queries by enabling mysql query logs and optimize them by creating indexes on possible search fields.

I also use my query to obtain the total count of records.
Is't possible catch the value of jqgrid_dist instead do another query?
If yes how?
Thanks in advance
