Drawing items in Listview control

Hi, all.  When I add items dynamically to a listview, the items are drawn
far apart horizontally and very close together vertically.  I need to draw
them closer together horizontally and farther apart vertically.  I tried
setting the ownerdraw property to true but the OnDrawItem event is not
called.  Is there a bug in the listview? Am I missing something very
obvious?
Any help with this will be greatly appreciated.

Gino.
