On the _ItemPopulate(object sender, EO.Web.NavigationItemEventArgs e) event, when a node that has a parent is clicked to be populated, it shows the parent as being null. However, the ASP Treeview does show the parent as existing.
I want to be able to expand a node and then recursively find the root node.
Thanks

Hi,
The parent node is intentionally omitted for both performance reason and to avoid confusions. Many users tried to modify the parent node during populate on demand and only to later realize that won't work. As a result e.TreeNode is always an orphan node during populate on demand.
The recommend practice for this is to always store some kind of key information in your TreeNode.Value. For example, you can store your "record_id" inside TreeNode.Value. You would then solely rely on this "record_id" to find all child records (for populating child nodes), or to find parent record (for looking up parent nodes), or to perform any other actions such as update/delete records.
Thanks!
