How to show the subroots (childroots) while clicking on a particular rootnode

I am using devexpress开发者_开发问答 xtratreelist in this I have a tree..now I want my form to work in sucha away that if the user clicks on a particular node all the subroots of that node shud be published on a list box or anyother control..How it can be done?

I haven't used the XtraTreeList control before but taking a quick look at the online documentation you should be able to use this node iteration example to loop over the relevant nodes and use the TreeListNode parameter to get more details than just simply incrementing the total count.
