    DataSourceColumnBinding productAmountBinding = new DataSourceColumnBinding("ExtendedPrice");
    pivotGridControl.Fields["fDifference"].DataBinding = new DifferenceBinding(
        productAmountBinding, CalculationPartitioningCriteria.ColumnValue, DifferenceTarget.Previous, DifferenceType.Absolute);
}
