TreeView Navigation UI

With its comprehensive client-side API and ability to handle a rich set of client-side events, the ASP.NET TreeView gives you total control over its behavior on the client. A variety of customizable UI elements and behaviors designed to give you meticulous control over the TreeView's runtime capabilities.

Data Binding Options

Hierarchical data presentation made easy. Designed primarily as a site navigation tool, our TreeView can be bound to any standard data source or to any object that represents a tree-like structure.

In addition to bound and unbound modes, the ASP.NET TreeView ships with a Virtual Data Loading Mode that significantly reduces both server load and start-up time when displaying complex or dynamically created hierarchies.

Callbacks (AJAX)

Load only what you need. Our ASP.NET TreeView control fully supports AJAX and can load the content from the server using a Callback.

As you would expect, this allows the TreeView to avoid the initial transfer of all node data to the client, optimizing web page load times.

Hot Track & Animation

Display visual feedback within your tree. Apply animation effects when a tree node expands/collapses. Our TreeView control allows you to associate navigation links for individual nodes, and to control the animation effect when a node is hovered/selected.

Section 508/WCAG Compliance

Controls that are a part of our ASP.NET Navigation and Layout Suite are designed to comply with Section 508 Standards and W3C's latest accessibility recommendations: WCAG (2.0) and WAI-ARIA (1.0).

Web Themes

In addition to over 20 built-in and easy-to-use web themes, you can use style properties and CSS for appearance customization. Templates are also available for fine-grain control over UI elements and control layout.

ASP.NET TreeList

Key ASP.NET controls in this subscription use semantic HTML to keep output clean and minimal. The semantic HTML markup means that web pages are lighter and faster, more search engine friendly and provide improved accessibility for screen readers.
