Treeview and contextMenu problem

Question

Hi Nice site you have here :D I have a TreeView. On a specific time i click the right mouse button, and a context menu pops up. After that, if i click on a Treeview node that is different from the treeview.selectedNode, how can i change the "clicked" node to be the selected one, or in alternative, how can i make some actions on the "clicked" node?? Can you help me with this. Thanks
