I have a treeview control which I am populating with two first levels that have two levels below them for a total of three levels. Everything has been working great until I added a third first level.
The new first level is expanded initially so the second level is visible. When I click the plus sign at the second level, it expands and the plus sign disappears. The other first levels don't do this so it must be a coding error on my part.
Does anyone have an idea of what is causing this?
