The level of nesting in the treeview hierarchy can easily be controlled using the LevelOfNesting property. For example when set to 2, the treeview is populated no further than the second level.

LevelOfNesting = "2"	LevelOfNesting = "3"

You can easily specify whether postings should be included (or excluded) from a menu using the combination of IncludePostings and HiddenPostings properties. When the IncludePostings property is set to true all postings specified by the StartChannel will be shown as treenodes. You can then hide some of the postings by specifying them in the HiddenPostings property.

HiddenPostings = "default"	HiddenPostings = "Stock Funds, Bond Funds"

In order to populate a treeview from a Resource Gallery all you need is to set the StartCannel property. When StartChannel is set to "Channels", all folders in the channels are shown as treenodes, otherwise only the specified folder is shown.

StartChannel = "/Channels"	StartChannel = "/Channel/FinacialSite/"

You can easily manage the state of a treeview, allowing it to retain the selected items during roundtrips to the server.

In addition to server-side load on demand through SQL or XML, RadTreeView introduces a powerful client-side load on demand mechanism, which allows you to populate child nodes on demand without postback to the server. The nodes, which are retrieved client-side cannot take part in server events, but only in client events like Href redirection and client-side drag-and-drop.

Expand the capabilities of your web-application with the novel drag-and-drop between treeviews functionality. The component generates NodeDrop server-side event, so its handler can perform specific actions, by fetching both the source and the destination drag/drop nodes.

With RadTreeView you can drop nodes not only on other treeviews but on any HTML element, textboxes, buttons, even Datagrids.

RadTreeView node structure can now be indexed by all search engines (Google, Overture/Yahoo, etc). The only thing that needs to be done is to make sure you are using Href navigation (URL navigation) instead of postbacks. If you are using Href, RadTreeView will render plain <a href=”…”> links, which are indexable by all search engines.

RadTreeView includes 3 accessibility features which make it fully "Section 508"-compatible. Those are the TabIndex property, the AccessKey attribute, and the LongDesc and Title/Alt attributes for links and images.

All functionality is supported on Gecko based browsers (Firefox, Netscape, Mozilla). Opera and Safari are supported as well (without the Context menus).

RadTreeView can be fully navigated using the keyboard. You can focus on a treeview with a predefined Alt+Key combination, navigate through the nodes, expand/collapse, select, and check/uncheck nodes.

RadTreeView fully supports node sorting. The only thing you need to do is to set the Sort property to one of the following values: Ascending, Descending, None.

RadTreeView supports binding to datasource (DataSet, DataTable) so you can easily populate a treeview instance with only a few lines of code. The built-in databinding mechanism supports auto-binding from a single self-referencing table with ID -> ParentID relation.

Expand the functionality of RadTreeView by adding context (right-click) menus to any treenode. Each context-menu item can fire both server and client events, and are also customizable through CSS.

To allow for easy appearance customization, RadTreeView uses "skins": a set of images and a CSS stylesheet that can be applied to the treeview structure elements (Nodes, line images). The product is shipped with a number of ready-to-use skins, including Office XP, Windows XP, and MSDN.

RadTreeView offers full support for .NET Framework 2.0 and Visual Studio 2005.

Another unique feature of RadTreeView is the ability for implementation of treeview combobox, similar to the Custom Links drop-down of RadEditor.

RadTreeView now provides complete XHTML compliance. The HTML markup of the component is fully XHTML 1.1 compliant.

RadTreeView provides special accessibility features and full keyboard support, which makes it fully compliant with "Section 508" and "Level A" (in accordance with the W3C Web Accessibility Guidelines 1.0).

You can now use the design mode of Visual Studio .Net to add/edit/remove treeview items, edit treeview templates and use databinding.

You can now embed any content inside a RadTreeView template, including HTML markup, ASP.NET server controls, or third-party controls. This provides virtually unlimited versatility as to the appearance and functionality of the treeview nodes.

When dragging a node to a part of the treeview which is hidden, the control will scroll up/down to that part automatically.

When you want to drop a node to a closed node of the treeview, the latter will be automatically automatically opened once the mouse pointer is held for a second over that node.

The RadTreeView nodes (RadTreeNode) provide a special collection called Attributes. You can store any number of attributes in the collection as name/value pairs.
