public static void PivotCalculations(PivotGridControl pivotGridControl) {                        
    DataSourceColumnBinding productAmountBinding = new DataSourceColumnBinding("ExtendedPrice");
    //Calculate a difference between the preceding and current value in the column.
    pivotGridControl.Fields["fDifference"].DataBinding = new DifferenceBinding(
        productAmountBinding, CalculationPartitioningCriteria.ColumnValue, DifferenceTarget.Previous, DifferenceType.Absolute);
}

Public Sub PivotCalculations(ByVal pivotGridControl As PivotGridControl)
            Dim productAmountBinding As New DataSourceColumnBinding("ExtendedPrice")
            pivotGridControl.Fields("fDifference").DataBinding = New DifferenceBinding(productAmountBinding, CalculationPartitioningCriteria.ColumnValue, DifferenceTarget.Previous, DifferenceType.Absolute)
