Masterpage Treeview SelectedNodeChanged and Style errors

[biker]

Help!?

Loss of formatting can be tolerated in this application, but for the menu to
quit working...well...

I have a treeview control on a masterpage.
- ShowExpandCollapse is True.
- DataSource is None.
- HoverNodeStyle, NodeStyle, ParentNodeStyle and RootNodeStyle are set
for desired values.
- Nodes are manually entered.
With the above settings, everything works fine...branches expand and
collapse, URL links work, etc.

I delete the nodes and set the DataSource to point to an XML file, setting
the Name Field = Name value in the XML file and the Value Field = Permit
value in the XML file, and, for CNode nodes, the URL Field = Target value in
the XML file...now the formatting set by the various style entries quits
working.

I change the URL Field to blank and set the Target field Target value in the
XML file...styles still do not work, and, of course, the links are gone, but
expand/collapse still works.

I create an event handler sub for the treeview SelectedNodeChanged event,
just an empty subroutine...The event fires each time I click on a tree node,
but, expand/collapse now affects the wrong nodes...not the one I click on.
The first parent node works, the 2nd does nothing, the 3rd does nothing, the
4th expands/collapses the 1st, the 5th works...you get the idea.

I add code to get the Target value of the SelectedNode, and redirect to that
URL. The SelectedNode points to the first leaf node within the group of leaf
nodes under a parent node...no matter which leaf I click on.

Here is my SelectedNodeChanged event handler, and a subset of my XML file:

Protected Sub tvMenu_SelectedNodeChanged(ByVal sender As Object, ByVal e As
System.EventArgs) Handles tvMenu.SelectedNodeChanged
If Validate_User(tvMenu.SelectedNode.Value, appsess.USER_ACCESS_CSV) Then
If tvMenu.SelectedNode.Target <> String.Empty Then
Response.Redirect(tvMenu.SelectedNode.Target)
End If
End Sub
