Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v24.2.dll

Declaration

C#

public class DifferenceBinding :
    DifferenceBindingBase

VB.NET

Public Class DifferenceBinding
    Inherits DifferenceBindingBase

Remarks

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

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

Example

The following code snippet illustrates the use of the Data Binding API to calculate a difference between the preceding and current value in the column:

Run Demo: Optimized Mode - Field Calculation Bindings

C#

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);
}

VB.NET

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)
        End Sub
