I'm trying to color the cells of a TIB_Grid depending on data values in the row

procedure ...DrawCell(Sender: TObject; ACol, ARow: Integer; Rect: TRect; State: TGridDrawState);

I can get the cell text using GetCellDisplayText(ACol,ARow), how can I get other values in the Row not displayed in the grid?

Accessing the TIB_Query current row doesn't work.

Paul
