After a sort operation is performed by using the OrderByExpression expression in the QueryExtender control, subsequent sort operations can be performed by using the ThenBy class on a different data field.
The following example shows how to sort data by the ListPrice field in descending order and then on the ProductID field in ascending order using the ThenBy type. This code example is part of a larger example provided in Walkthrough: Filtering Data in a Web Page Using Declarative Syntax.
<asp:OrderByExpression DataField="ListPrice"
Direction="Descending">
<asp:ThenBy DataField="ProductID" Direction="Ascending"/>
</asp:OrderByExpression>
