Hi,
The OnDrawItem event in TRzListView is inherited from the TListView control. That is, the event is generated by the inherited behavior of the TListView (and more precisely, the TCustomListView) class. According to the Help for TListView, the OnDrawItem event only fires when CustomDraw is also set to true. You may wish to take a look at the other drawing related events such as OnAdvancedCustomDraw, OnAdvancedCustomDrawItem, etc.
