Do not use ExpandAllNodes() in your ViewModel. It is a function of the View and the ViewModel shouldn’t know about the View.
Add a property (boolean?) to the ViewModel that indicates whether or not the Tree should be expanded and bind the state of the Tree to that property.
I am not quite sure what Treeview control you are using but is you cannot bind the state of the Treeview you could have a change of the property in the ViewModel cause a method call to expand the nodes.
