I've noticed that if you use custom code to set the root folder of a list or library control, the new folder command does not create a new folder in the desired place, but at the root of the library.
e.g. if library control is set dynamically to ProjectDocuments/1234
clicking the new folder creates ProjectDocuments/new folder,
but I want it to create ProjectDocuments/1234/new folder.
Is there a way to make the new folder/up one folder buttons work relative to the root folder that has been dynamically set?
