Tree view that dynamically updates

I am trying to create a tree view that re-populates itself when a user adds something somewhere else on the page. I am stuck with an existing data source which is a list of folders and links in folders. So each node needs to be a folder or a link inside a folder. Elsewhere on the page the user can add a new link and/or folder and that means the tree should get updated accordingly. What's the best way to tackle this?

You need to call the data bind function of the Treeview on successful data entry.
Let me know if this helps else please post your code.
