hi. I have a situation, a grid with a memtable in the back. I want to analyze all de field from the 1 line, column by column, after 2 line. 3 line. If in each column i have a condition. If the cell is ok, (with value, not null, numeric/string) the cell color is white, if not i want to color to red. Color the cell, not the column, noy the grid. Each cell :) like a "chess board ".

Please give me a little example.
Thanks.

Hello

You can use TDBGridEh.OnGetCellParams event to set background color like this:

Code:
procedure TForm1.DBGridEh1GetCellParams(Sender: TObject; Column: TColumnEh;
  AFont: TFont; var Background: TColor; State: TGridDrawState);
begin
  if TColumnEh(Column).Field.AsString = '' then
    Background := TColorRec.Lightsalmon;
end;
