How to highlight alternate rows in a TListView

Answer:

The following will draw all alternate lines with yellow text on blue background. It 
uses the OnAdvancedCustomDraw events of the listview. As a bonus you get full 
highlighting of selected lines.
1   
2   procedure CheckPaintstage(Stage: TCustomDrawStage; itemIndex: Integer; canvas:
3     TCanvas);
4   begin
5     if Stage in [cdPrePaint, cdPreErase] then
6     begin
7       if Odd(itemIndex) then
8       begin
9         Canvas.Brush.Color := clBlue;
10        if Stage = cdPrepaint then
11          Canvas.Font.color := clYellow;
12      end
13    end;
14  end;
15  
16  procedure TForm1.ListView1AdvancedCustomDrawItem(Sender: TCustomListView;
17    Item: TListItem; State: TCustomDrawState; Stage: TCustomDrawStage;
18    var DefaultDraw: Boolean);
19  begin
20    if not (cdsSelected in State) then
21      CheckPaintstage(Stage, item.Index, sender.canvas)
22    else
23      Sender.Canvas.Brush.Color := clHighlight;
24  end;
25  
26  procedure TForm1.ListView1AdvancedCustomDrawSubItem(Sender: TCustomListView;
27    Item: TListItem; SubItem: Integer; State: TCustomDrawState; Stage: 
28  TCustomDrawStage;
29    var DefaultDraw: Boolean);
30  begin
31    if not (cdsSelected in State) then
32      CheckPaintstage(Stage, item.Index, sender.canvas)
33    else
34    begin
35      Sender.Canvas.Font.Color := clHighlightText;
36      Sender.Canvas.Brush.Color := clHighlight;
37    end;
38  end;
