I need to reverse loop through the parent nodes of a node to get the text of each node.  So if my node structure is parent->child1->child2 I need to go loop child2->child1->parent.  Any suggestions?

Hello,

Please review the following articles, which explain in detail the Client API of the TreeView control, and how you can use it to traverse the tree in whichever manner you need:

I needed to do this serverside and start with a child that was checked and go in reverse through all it's parents to get the text of each one.  I accomplished this by using (vb):

dim nodeText as string = childnode.text
If Not childnode.ParentNode Is Nothing Then
    Dim parentnode As RadTreeNode = childnode.ParentNode
    Do While Not parentnode Is Nothing
          nodeText = parentnode.Text & "-" & nodeText
          parentnode = parentnode.ParentNode
    Loop
End If
