Asp.net Hierarchical DataBound Controls

Asp.Net CS By Example 22 December 2019

Hierarchical DataBound Controls:

A hierarchical DataBound control can display nested data items. For example, we can use
hierarchical DataBound controls to display the folder and page structure of our website,
the contents of an XML file, or a set of master/detail database records.

The ASP.NET includes two hierarchical DataBound controls:
1) Menu—Displays data items in a static or dynamic menu.
2) TreeView—Displays data items in a tree.

The Menu and TreeView controls are bound to an XmlDataSource control,
which represents the XML file.
