I've been away on vacation for the past week and I see that you've gotten no responses to your question ... have you resolved the issue? Have you looked at the designer-generated code to see how the items actually got added? (off the top of my head, I don't know and I haven't added items to combos in this manner in the past).

>I have a sub-class of a user control that has a combobox in it. In the sub-class I have a set of items entered in the list via the collection in the IDE. I then drop the sub-classed control on a form and run it. No problem. I then go back to the sub-class in the IDE and add items to the combo dropdown collection and change some of the item’s names, values etc. Rebuild the entire solution with all projects. Run the form and only the original set of combo items shows up in the dropdown. The instantiated combo objects are not refreshed with the additions/changes to the dropdown list. The already placed object of the sub-class does not reflact the changes made in the sub-class.

But I have removed them all to external folders and rebuilt the solution to no avail. Where in the world could the info be kept that gets built into the instantiated objects? Any info on this would be appreciated.
