Node.parentnode.nodes.remove(node) is removing parent node when the top child node is removed.

I'm trying to remove a child node from a RadTreeView Parent node. This is working fine as long as it is not the top child node under the Parent.

Parent

>child1

>child2

>child3

>child4

If I remove child2, 3 or 4; it works. But if I remove child1, the Parent is removed along with any remaining child nodes.

The behavior I expected is that I should be able to remove any of the child nodes in any order and the Parent node should be removed only when the last remaining child node is removed - but even that is debatable since what if I wanted to add more child nodes to the Parent node after removing everything?


Thanks for any help.

What I have tried:

Dim remove_node As RadTreeNode = rtvClientSpecs.FindNode(Function(x) x.Value = e.CommandArgument.ToString())
remove_node.ParentNode.Nodes.Remove(remove_node)
