I've been trying to use the DNNTree Control but I can't get it to select a node when a user clicks on it...

Here is the best exampled I've come up with:
1.<dnn:DnnTree ID="DNNTreeTest" runat="server" PopulateNodesFromClient="true"
2.    CollapsedNodeImage="../../images/Plus.gif"
3.    ExpandedNodeImage="../../images/Minus.gif">
4.    <TreeNodes>
5.        <dnn:TreeNode ClickAction="None" Selected="true" Key="1" Text="Test1" Enabled="true" LeftHTML="abs" RightHTML="def"  />
6.        <dnn:TreeNode ClickAction="None" Selected="false" Key="2" Text="Test2" Enabled="false" />
7.    </TreeNodes>   
8.</dnn:DnnTree>

When this is rendered, neither node is selected and the second one isn't disabled... What am I missing? (I've even looked at the FileManager code but I don't see anything.)

My next test:
01.<dnn:DnnTree ID="DNNTreeTest" runat="server" PopulateNodesFromClient="true"
02.    CollapsedNodeImage="../../images/Plus.gif"
03.    ExpandedNodeImage="../../images/Minus.gif"
04.    CheckBoxes="true" CheckBoxMode="SingleSelect">
05.    <TreeNodes>
06.        <dnn:TreeNode ClickAction="None" Selected="true" Key="1" Text="Test1" Enabled="true" LeftHTML="abs" RightHTML="def"  />
07.        <dnn:TreeNode ClickAction="None" Selected="false" Key="2" Text="Test2" Enabled="false" />
08.    </TreeNodes>   
09.</dnn:DnnTree>
Note that in this one, I put in CheckBoxes so you can at least see that a node is selected, but I would like to highlight the node to make it simpler to the user. Ideas?

So, it's been 2 months and no answer... Maybe this is posted in the wrong place?

Does the DNNTree control require jQuery to function or javascript in general? (for the selection highlight)

Now I've added a DnnTree to a DataGrid EditTemplate and it doesn't even Render =/
(I think I'm making this harder than it is but I'm lost currently...)

FINALLY!!! I ended up putting a search engine on the DotNetNuke Source code and looked for the CSS class name... after a little bit of digging, I found there is a module.css in the same folder as the filemanager module... Then I searched for module.css and found in the "WhatsNew.ascx" file that DotNetNuke added the automatic loading of module.css within the module directory.

So, for a quick test I copied the module.css from the filemanager to my local modules' source directory and BOOM - it works! I got highlights and selected CSS styles applied!!!

3 Months, but I found the solution!!! =D
