About RadListBox for ASP.NET AJAX

RadListBox is a powerful ASP.NET AJAX control to display a list of items. It allows for multiple selection of items, reorder and transfer between two listboxes. Drag and drop is fully supported as well. You can easily control the appearance by arranging the buttons in different layouts or changing their text. Icons and checkboxes are also supported within the listbox items. The RadListBox implements a highly efficient semantic rendering, which uses list items and CSS instead of tables. As a result the HTML output is significantly reduced, which dramatically improves performance. The control can also be bound to all ASP.NET 2.0 declarative datasources (ObjectDataSource, XmlDataSource, SqlDataSource, etc) as well as the ASP.NET 3.5 LinqDataSource. Binding to XML strings as well as automatic database updates are fully supported. RadListBox control has a rich client-side API and comprehensive set of events guaranteeing full control over various functions performed on the client. You can easily add/delete/update items at the client side and all the changes will be persisted on the server as well. The rich client-side API provides unbeatable performance and desktop-like experience. RadListBox is shipped with a rich set of skins that allow you to easily build slick interfaces with the look-and-feel of Windows Vista, Office 2007, Outlook, etc. The skins can be easily switched using a single property.

The control’s full support for drag-and-drop functionality enables users to transfer and reorder items, as well as perform multiple selection. RadListBox implements a highly efficient semantic rendering, by using list items and CSS instead of tables. This results in significantly reduced HTML output, which dynamically improves performance.
