RadTabStrip for ASP.NET AJAX Version Q3 2008 released 11/25/2008 (release history)

The DataBindings collection lets you provide different sets of data bindings to the tabs on different levels of the tabstrip. You can even bind the tabs on each level of the tabstrip from different tables in a DataSet.
This example demonstrates how to use databindings to apply declarative mapping of data fields to the tab properties.

        <telerik:RadTabStrip 
            runat="server" 
            ID="RadTabStrip1" 
            DataSourceID="AccessDataSource1" 
            DataFieldID="id" 
            DataFieldParentID="parentID">
        <DataBindings>
            <telerik:RadTabBinding TextField="Text"  />
            <telerik:RadTabBinding TextField="id" Depth="1" />
        </DataBindings>
        </telerik:RadTabStrip>
