    Inherits MovingCalculationBindingBase

Remarks

To bind a PivotGrid field to the result of the calculation in Optimized mode, do the following:

1. Create an instance of the MovingCalculationBinding class.
2. Set the Source property set to the DataBindingBase descendant instance.
3. Specify the window frame and calculation settings.
4. Assign the MovingCalculationBinding instance to the PivotGridField.DataBinding property.

Example

The following code snippet illustrates the use of the Data Binding API to calculate the average of the preceding, current and following values in the column:

Run Demo: Optimized Mode - Field Calculation Bindings

C#

public static void PivotCalculations(PivotGridControl pivotGridControl) {                        
    DataSourceColumnBinding productAmountBinding = new DataSourceColumnBinding("ExtendedPrice");
    //Calculate the average of the preceding, current and following values in the column.
    pivotGridControl.Fields["fMovingAverage"].DataBinding = new MovingCalculationBinding(
        productAmountBinding, CalculationPartitioningCriteria.ColumnValue, PivotSummaryType.Average, 1, 1);
}

VB.NET

Public Sub PivotCalculations(ByVal pivotGridControl As PivotGridControl)
            Dim productAmountBinding As New DataSourceColumnBinding("ExtendedPrice")
            pivotGridControl.Fields("fMovingAverage").DataBinding = New MovingCalculationBinding(productAmountBinding, 
        End Sub
