Telerik ListBox for ASP.NET 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.

Features

Semantic Rendering for Minimal HTML

The Telerik ListBox control 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.

Flexible Databinding

RadListBox can be bound to all ASP.NET 2.0 declarative datasources (ObjectDataSource, XmlDataSource, SqlDataSource, etc) as well as to ASP.NET 3.5 (LinqDataSource and EntityFramework).

Drag & Drop Behavior

RadListBox rich drag & drop functionality allows you to perform various operations: reorder items; transfer items from one listbox to another; move items on any HTML element, textboxes, buttons; auto-scroll on drag, etc.

Items Reordering

RadListBox allows you reorder items both through drag and drop or using the up and down buttons. The reorder buttons can be added to either side of the ListBox and are fully stylable.

Multiple/Single Selections

The Telerik AJAX ListBox allows you to select from a list of items, with the option to select a single or multiple items from the list. The control fully supports checkboxes, which are displayed next to the Items.

Flexible Layouts

RadListBox allows for various layout customizations. You can specify the size of the box, the position of the buttons, the text and background color style of each item, or add an icon to the item’s text.

Template Support

You can embed any content inside a RadListBox template, including HTML markup and ASP.NET server controls, as well as other third-party controls. Controls can be nested both in Visual Studio .NET Design mode and manually with the code.

Keyboard Support

RadListBox fully supports keyboard navigation with Shortcuts, Access Keys and Arrow-key navigation for selecting items, checking items and deleting items.
