I have been trying to get a content tree to render inside my custom datatype to alow the end user to select nodes. I can see that there is a TreeControl.ascx file but it fails to loade. I can find a BaseTreePicker and BaseTree and alot more that sounds like hey this is the thing i need but nothing seems to work, does any one have some words of advice on how to render the content tree inside a custom datatype.

Maybe some javascript umbManager.RenderTree(startnode); <--- that would be awsome 

HFIS but HFYR if u can help :)
