I began looking at DNN one week ago. I have viewed 16 videos, bought 4 Book, read most of it. Installed DNN on a server and have a couple of test portals set up and have done some modifications, etc. I have been programming for many years in .NET but am not a high end super technical programmer. I depend, very much, on examples, intellisense etc.  
For me to use DNN I really need to be able to use a Treeview. I have read the PDF's on the Treeview by Shaun. One was from 2005 and one from 2006. They are very technical and not about a control that is easy to use. I am wondering if they are relevant documents due to their age. 
I have also downloaded the Webcontrols examples.
Many of the posts regarding Treeview go unanswered. I am not sure why but it is leading me to think that this control is not supported or  just "a pain".

So... here is my question:
Can you tell me if the Treeview is a viable control in DNN? I want to use it to "tree" data on a left pane and, at the last level, be able to click on a bottom level item to display a "product" per say on a right pane. The data to fill the tree will be coming from a SQL database and from a few related tables. The size of the data is not very big. First level 10 nodes, second level 20 nodes max per parent and the the third level 50 max per parent. Any idea if this is doable in DNN with their Treeview control?  thank you. Michael Moore. St Paul
