RadTabStrip's content is separated from the tab labels. The tabs represent only the labels and not the content below them. The content is rendered independently of the tab, for example using a Radmultipage, hence giving the developer more freedom in the authoring process.

Since the tabstrip content is now separated from the labels, developers can easily build multilevel tabstrips using nested XML tag declarations.

RadTabStrip v2.0 delivers the convenience of desktop applications to the web with keyboard support - access keys and arrow-key navigation.  

RadTabStrip fully supports foreign languages.  To localize the Tab labels, you need to create a separate Content File for each language and then load it dynamically using the LoadContentFromXmlFile method.

They are used to group the tabs of RadTabStrip into two or more categorizes. With the property IsSeparator you can define a tab to act as a separator. You can then define its size using the Width property.

RadTabStrip now provides a number of expand effects like fade, slide, etc. (Internet Explorer only)

You can achieve a wide variety of TabStrip configurations by combining the 8 generic types supported by RadTabStrip.

Complex graphic designs can be easily achieved using background images. Simple-image backgrounds are easier to set, while the overlapping ones allow you to simulate sophisticated graphic effects, like shadows, perspective, etc.

All content that will appear inside the Tab Area must be defined in a <ContentTemplate>. It can accommodate regular HTML or other controls, including other TabStrips (Nested TabStrips).

Since the Tab Labels accept HTML formatting, you can easily add icons or other images using the <img src=""> tag in the Label name. This is a very convenient approach as you can place icons before or after, without having to specify properties, etc.

The visual appearance of the strip, the content area, and the individual Tabs is configured completely through CSS classes. There are 5 main CSS classes and 4 additional ones for fine-tuned manipulations.

RadTabStrip has full support for the Design mode of Microsoft^© Visual Studio .Net. This allows you to build, customize, and populate the tabstrip in a convenient WYSIWYG environment.

RadTabStrip v2.0 features a richer server-side API. For example, the new tabstrip can now be bound not only to DataSet, DataTable, and XML document, but also to DataView.

When a tab is defined as a separator, the style assigned to its UniqueDefaultCssClass property will be rendered as its CSS class. As a result separators now can have styles.

A new property called NavigateBaseUrl is added to the RadTabStrip class. It gets or sets the base url address, to which the NavigateUrl values of the individual tabs are added.

Telerik RadTabStrip v3.0 introduces a new highly efficient rendering technology, which builds the HTML markup as a set of list items instead of tables or DIV's. As a result, the control's output is reduced by more than 70%, which directly transfers into faster load times. All upcoming major releases of the Telerik navigation controls will use the new rendering technology, allowing you to benefit from the most optimized menu, panel and treeview controls on the market.

Developers can now build and customize RadTabStrip in a minute and entirely in design mode, using the new visual builder. It allows you to define the tabstrip structure, apply skins, and set individual item properties.

To enable effortless development of the client-side tabstrip behavior, RadTabStrip provides a much richer API that almost completely matches the model of the server-side API.
