1.U_tvs
Service-based TreeView visual user object ancestor. This object uses DataStores to display data in a TreeView.
U_tvs is a self-updating object.
2.U_lvs
Service-based ListView visual user object ancestor. This object uses DataStores to display data in a ListView.
U_lvs is a self-updating object.
U_lvs replaces u_lv U_lv is the ListView control supported in earlier PFC versions. Although PFC still provides u_lv, it's best to use u_lvs.
所以,u_tv和u_tvs，u_lv和u_lvs是一个老版本一个新版本的pfc控件,建议用后者.pfc实例中有二者的实例可参考
