Hi.
I make a simgle database test application with Firebird 2.1 Database (the single select instruction retrieve 40000 database records in this test), a test form with dbnavigator, dbgrid and tsqlquery component. I surprised to view than dbgrid loads database record dinamically "on demand" while moving . It is normal ?.
In a similar test with ZeosLib components, all records are reading at same time en dbgrid and the test is very slow.
Thanks !
