I cannot get the TreeView control to work on webparts or even a clean aspx page on my sharepoint server. The pages shows ok as long as I set the TreeView to visible=false, but when I set it visible=true I get the "page not found" 404 error, and no part of the page is displayed.
I have done everything it says in the readme file accompanying the IE web controls download. So I suspect that Sharepoint is the problem. Do I need to do anything extra to use the TreeView control with SPS?
Any thoughts?
