Hi,

I want to color the rows like this:

if odd(item.Index) then
Sender.Brush.Color := clSilver
 else
 Sender.Brush.Color := clWIndow;

But I have allready code in the ListView1CustomDrawItem.
Where should I implement it?

Greetings, Peter Kiers
procedure TMainForm.ListView1CustomDrawItem(Sender: TCustomListView;
  Item: TListItem; State: TCustomDrawState; var DefaultDraw: Boolean);
Var
 R:TRect;
 i,NC:integer;
 TotWidth:Integer;
begin
 DefaultDraw:=False;
 With Sender.Canvas do
  begin
   if Item.Selected then
    begin
     Brush.Color := clNavy;
     Font.Color:= clWhite;
    end else
    begin
     Brush.Color := clWIndow;
     Font.Color:= clBlack;
    end;
   FillRect(Item.DisplayRect(drBounds));
   R:=Item.DisplayRect(drLabel);
   TextRect(R,R.Left,R.Top,Item.Caption);
   NC:=Min(Item.SubItems.Count+1,TListView(Sender).Columns.Count);
   if NC<2 Then Exit;
   TotWidth:=Sender.Column[0].Width;
   for i:=1 to NC-1 do
    begin
     TextOut(R.Left+TotWidth,R.Top,Item.SubItems[i-1]);
     TotWidth:=TotWidth+Sender.Column[i].Width;
    end;
  end;
end;

   if Item.Selected then
    begin
     Brush.Color := clRed;
     Font.Color:= clWhite;
    end else
    begin
     if (Item.Index And 1)=1         // Add a test for index is Odd here
      Then Brush.Color := clCream
      Else Brush.Color := clWhite;
     Font.Color:= clBlack;
    end;

Ok, I could have used the Odd() function instead of that binary test for first bit ... Old habits die hard
