How do I expand a single node in RadTreeListView control

[Frank]

Is there a way I can expand only a single node in RadTreeListView control ?

Hi,

In order to expand a single node in the RadTreeListView, you could use the ExpandHierarchyItem method. 

Kind regards,

Thanks. That worked. But I how do I expand all the root nodes ?
e.g

ContainerA
         SubContainerA
         SubContainerB

ContainerB
         SubContainerA

ContainerC
         SubContainerA
         SubContainerB

I did  ExpandHierarchyItem(treelistview.Items[0]) and this expanded the first root node which is ContainerA.
I want to be able to expand the remaining root nodes as well i.e ContainerB and ContainerC.

Is there any property that tells if the node is a root node ? Number of SubContainers is not constant.
