Introduction
The
ASP.NET TreeView control is a powerful server-control for rendering
TreeView UI, as shown in the figure below. It supports a variety of
programming models, from statically-defined trees, to dynamically
constructed trees, to databound trees. The TreeView's rendering is fully
customizable, allowing for a wide-range of look-and-feels for the
control.
