CustomDrawSubItem is a Boolean function used to custom draw a sub-item on the list view control. The OnCustomDrawSubItem and OnAdvancedCustomDrawSubItem event handlers are signalled (when assigned) to perform the drawing operations needed for the item, sub-item, stage, and state arguments.
OnCustomDrawSubItem is signalled when Stage contains cdPrePaint. OnAdvancedCustomDrawSubItem is signalled for any of the values in the TCustomDrawStage enumeration.
