Hi there, what you want should be possible, the exact implementation will depend on where in the tree you are when you want to get the parentId. The key is that I don't think you can use editorState, instead you have to inject appState and treeService into your angular controller

This will get the top most node of the current tree:

var rootNode = appState.getTreeState("currentRootNode");

This will get the current selected node in the custom tree

var selectedNode = appState.getTreeState("selectedNode");

If the current selected node has a parent the parentId property will have the appropriate value.

If you want to do more the treeService has various methods to get children & descendants taking section name and node (retrieved using methods above) as arguments.

See the tree service in the umbraco source here for details https://github.com/umbraco/Umbraco-CMS/blob/d50e49ad37fd5ca7bad2fd6e8fc994f3408ae70c/src/Umbraco.Web.UI.Client/src/common/services/tree.service.js

Thanks a lot Ian :)
