The number of nodes i get in 0.
I'm runnig this code for: http://demos.telerik.com/silverlight/#TreeView/HierarchicalTemplate

var myApp = Pages.TelerikTreeViewFor.SilverlightApp;Telerik.WebAii.Controls.Xaml.RadTreeView tree = myApp.XTreeViewRadtreeview;Log.WriteLine(tree.AllNodes.Count.ToString());'11/21/2013 11:34:39 AM' - LOG: 52
RadTreeView has a built in "AllNodes" member that you can then call Count on.
There is also an "RootNodes" which would return a count of 4.
Hopefully this is what you were looking for.

Hi Daniel,
Thanks for your quick answer.
Unfortunately the solution you provided doesn't work.
The problem is that the first time I navigate to http://demos.telerik.com/silverlight/#TreeView/HierarchicalTemplate , only 7 nodes of the tree view appear.
If i run the following script it will find only the first 7 visible nodes.
I would like to find all the nodes after expanding the tree (which should be 52 nodes in this example).
Is this possible ?

I realize now the mistake I made which resulted in mine working. The visual tree had already been refreshed as I re-ran the selected step only.
Here is how to fix it:
important line is "tree.Refresh()" which causes the Visual Tree to refresh, updating the node count. You may need the sleep depending on how fast the Silverlight app refreshed.
Here is the run log:
