TreeView with DropdownList

Question
System.Web.UI.WebControls.TreeView shows hierarchical data in an expandable tree view with the possibility to have a checkbox next to each node.
I want something similar, but I need to render a DropDownList at each node, so I can have more than two choices (checked or unchecked).
Is there a way to do this with a TreeView?
Or is there another free control that does it?
Solution
I don't know about other free controls, but with a TreeView you can't do it w/o creating your own version or taking over rendering. The TreeView does not use Controls collection and does not provide a way to inject anything or change its render output.
