I am using get_allNodes() and it appears to only return root and expanded nodes (it's not returning any children of collapsed parent nodes). At least, this is the count that nodes.length is giving me. Is this expected behavior?
I have tried to reproduce the problem you experience, but to no avail. Could you elaborate a bit more about the exact your scenario? I prepared a sample project, where you could observe the behavior of the RadTreeView control along with the usage of the get_allNodes() client-side method.
Please find the sample attached.
All the best,
