Hi Richard,
The required feature can be met using ClientSideObjectModels of TabStrip and Multipage which provides rich set of properties and events.
Tab item can be selected by passing the TabItem element which is to be selected as a parameter in the TabStrip onclick event. On Browser page load event, Top root item element ids are cached in an array and the required TabItem element can be get based on the multipage selected index.
Please refer the below sample which illustrates the above.
