Very strange Einar. I copied your class and collection code into my test form. It worked fine. I'm not sure where else to look.

>Bonnie,
>I still can not get it to "refresh" even when setting the SataSource to null and then setting it back to my collection. I can see through the debugger that the values in the collection has changed. Something even more strange happend once I made the code change, the selected index in the listbox does not appear to change, i.e. the blue hightlighted row does not change, but the selectedindexchanged even fires. Very odd. I am starting to think that I might use a datatable instead <s>, but before I do I would still like to figure this out.
