How can I disable editing on the desired nodes? Tried through CustomRadTreeViewEditor as below but without success.

public override void BeginEdit()
        {
            TreeNodeElement nodeElement = this.OwnerElement as TreeNodeElement;
            if (nodeElement.Data.Level == 0)
            {
                base.EndEdit();
                return;
            }
            base.BeginEdit();
        }

Hello, Serg, 

RadTreeView offers the Editing event which is about to be fired when the user tries to edit a node. You can cancel this event if the edit operation is not allowed. If the event is canceled, no further action takes place. Thus, you can disable editing on the desired nodes.

The following help article is quite useful about getting familiar with the editing lifecycle in RadTreeView: https://docs.telerik.com/devtools/winforms/controls/treeview/editing/editing-nodes 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
