As explained at http://www.telerik.com/forums/paging-a-treeview, paging in a treeview is not support. However, this feature would be highly useful for nodes that have hundreds of children, when the user may not want to way for all of them to be loaded or displayed at one time. See by contrast Webix pager for trees - http://docs.webix.com/api__link__ui.tree_pager_config.html
