treelistview

I'm using an TreeListView (a sub type of ObjectListView) in my current project. Each item in the list is given an icon, but the icon my vary depending on the state of the item. For example if the item is readonly I want to use an icon with a little lock symbol.

When the items are first added to the TreeListView the icons are show correctly, yet later when the state of an item changes the icons are not updating. How do I force the control to regenerate all the icons?
