NavigationBar Structure for ASP.NET AJAX

KT.UI NavigationBar control consists of a hierarchy of items, which means it displays in the mode of top root items and childe items. The items on child level will be exposed as long as the root item on the previous level is expanded. Here, we give the brief introductions to these two items.
  • Root Items: Root Items mean the items at the top level, and these items are always visible on web page. We can set root items by using Items property of the navigation bar.
  • Level Items: Each root item may have a set of child items, which can be called level items and child items. The children of the root items are always considered level 1 items. Children items can be set and added by using the Items property of the root item (PerNavigationBar.Items). Child items may have their own sets of child items. And children of level 1 items are considered level 2 items; thus, logically speaking, children of level 2 items are considered level 3 items; and so on.
