add nodes/cells in runtime dotnetbar advtree

[ud2008]

I have a question.

How can I create a outlook style addressbook using advtree (dotnetbar).
The group (root) node can be add by a textbox and after that the root is selected and through textboxes I can add a fullname and an emailaddress (which should be in the outlook style with multicolumns (see link below).

Advanced .NET C#, VB Multi-Column TreeView Control

There is no documentation from devcomponents on how to do this.

Does anyone of you guy's know how to do this?

Thanks
