I am using radajaxmanager in master. What I have is in left pane there is a radtreeview with Node expandmode=server. On the right pane I have radmulitilage which loads different usercontrol in codebehind. What I want to achieve is update radmulitiPage on right ONLY on nodeclick of radtreeview in left pane and not onnodeexpand. In ajaxproxy I specify the eventname but still refreshes right pane radmulitilage on any click in treeview. Thanks for help !
