Title: How to get different background color of DBGrid for odd and even rows (1)
procedure TForm1.DBGrid1DrawColumnCell(Sender: TObject;
const Rect: TRect; DataCol: Integer; Column: TColumn;
State: TGridDrawState);
var
test1: Real;
RowNo: Integer;
begin
with (Sender as TDBGrid) do
begin
if (gdSelected in State) then
begin
// color of the focused row
Canvas.Brush.Color := clblue;
end
else
begin
// get the actual row number
rowno := Query1.RecNo;
// odd or even ?
test1 := (RowNo / 2) - trunc(RowNo / 2);
// If it's an even one...
if test1 = 0 then
begin
farbe := clWhite
end
// ...else it's an odd one
else
begin
farbe := clYellow;
end;
Canvas.Brush.Color := farbe;
// font color always black
Canvas.Font.Color := clBlack;
end;
Canvas.FillRect(Rect);
// manualy output the text
Canvas.TextOut(Rect.Left + 2, Rect.Top + 1, Column.Field.AsString);
end
end;
