(SOLVED) Speed up a dbgrid with so many lines
«

Hi guys, I have a dbgrid that must display 10000 records. But it is very slow (over ten seconds). Is there any parameter that can speed up loading? Something that just loads me a few records at a time based on the scrollbar?
Thank you

I solved with
TZQuery.FetchRow:=10;
It was really trivial! Sorry
