Iam trying to develop an application in WPF, where a TreeView is to be designed without the crossmarks; instead there will be buttons with icons assigned to them individually. Secondly, whenever a node(button)-- say Node1 is clicked only the child nodes of that node(Node1) are to be displayed. If I scroll and click on another node, that node's childnodes to be displayed, the former node (Node1) automatically collapses.
