 <p>This example demonstrates how to create an ASPxPivotGrid and bind it to data via code.</p><p>In this example, the ASPxPivotGrid and AccessDataSource instances are created and initialized in code. The Pivot Grid is bound to data by assigning the AccessDataSource instance to the ASPxPivotGrid.DataSource property. Then the ASPxPivotGrid.RetrieveFields method is used to create pivot grid fields for all data source fields.</p>
