Description
Occurs when a subitem must be rendered in an owner-draw list view.
Write code in an OnCustomDrawSubItem handler to draw to the subitems that appear in additional columns to the right of each item when ViewStyle is vsReport. Use the list view's Canvas property as a drawing surface. Unlike the OnDrawItem event, the list view receives this event even if the OwnerDraw property is False.
Note: OnCustomDrawSubItem occurs immediately prior to the rendering of each subitem. To augment the default drawing process at other stages (such as after the subitem is drawn), use the OnAdvancedCustomDrawSubItem event instead.
OnCustomDrawSubItem is an event handler of type Vcl.ComCtrls.TLVCustomDrawSubItemEvent.
