Examples

The following example shows how to sort data by the ListPrice field in descending order and then by the product ID field in ascending order. This code example is part of a larger example that is 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>  

Remarks

The OrderByExpression object sorts the data in a data field. Subsequent sort operation can be performed on a different data field by using the ThenByExpressions property.
