Hello smith,
You can get all the root level items from the RadTreeView.Items property. To disable them just set the IsEnabled property to false.
About your second question - when you delete a node - you are deleting its child items also. If you want to keep the child items you should first move them somwhere else in the tree and then to delete the parent node.
I hope this helps!

Hello smith,
You can use the PreviewEditStarted event of the TreeView item to handle it and to stop it for the root items.

For the Drag and drop you can use the PreviewDragStarted event in the same manner.
