I am stuck again !

Trying to draw my own cell font colours.
If I use 'ondrawcell' I have to get the 'text' for each row & col from the
dataset
which is a Tib_Query normally connected through a tib_datasource.

Which is the controlling force. The dataset or the grid?
If I say 'qry.open' its data would normally appear in the grid. Does the qry
do a scan and fill the grid or does the grid do a re-draw and pull the data
from the query?

Anyway some guidance on how to do it, would be helpful.
Regards Dave.
