The problem is that if the user clicks on a TListView outside the items the current 
selected item is deselected. I want my TListView to always keep one item selected 
so this never happens. What is the easiest way to accomplish this?

Answer:

1   { ... }
2   Listview1.HideSelection := False;
3   { ... }
4   
5   { ... }
6   var
7     FPrevItem: TListItem;
8     { ... }
9   
10  procedure TForm1.ListView1MouseDown(Sender: TObject; Button: TMouseButton;
11    Shift: TShiftState; X, Y: Integer);
12  begin
13    if not Assigned(Listview1.Selected) then
14      Listview1.Selected := FPrevItem;
15  end;
16  
17  procedure TForm1.ListView1Change(Sender: TObject; Item: TListItem; Change:
18    TItemChange);
19  begin
20    FPrevItem := Item;
21  end;
