I have treeview
I am dropping a node to the root (no parent)
var destinationNode = args.get_destNode();
destinationNode has value and not a null
but
destinationNode.get_nodes().get_count() is equal zero
how this make sense
I want to do some validation before dropping so i wamt to know the children of the parent node
in my case the parent should be null (as it is a root)
to avoid this problem I will check the level and if it is zero I will check all the root noed but who can I get them?

Hi Hamdy Ghanem,
In the ticket info I see you are using the latest version 2010.2 713. There is a new property called get_allNodes(). When called from a node it will return all child nodes of a node. You can use it to find all the child nodes of the root node and then check the level of each of them as you want.
Please let me know if this helps.
