FetchAll := False;
FetchRows := 50;

3.
OraQuery.Open;

4.
when mouse wheel down last record..
I want next fetch 50 record.
but, now..
no more wheel down.

5.
I want code:
-----------------------------------
if (wheel down) and (oraquery.eof) then
oraquery.nextfetch; // my set 50record.
-----------------------------------
how?
please help.

thanks for read.

The TDBGrid component does not support mouse wheel correctly. You can try to find some third-party grid component that supports moving to the next record using mouse wheel.

thank you read.

I using DBGrid component is NxDBGrid. third-party component..
and support mouse wheel.
