WindowExpressionBinding Class

Defines the calculation that uses a custom string expression with window functions.

Namespace : DevExpress.XtraPivotGrid

Assembly : DevExpress.XtraPivotGrid.v25.2.dll

NuGet Package : DevExpress.Win.PivotGrid

Declaration

C#
VB.NET

csharp

public class WindowExpressionBinding :
    WindowExpressionBindingBase

Public Class WindowExpressionBinding
    Inherits WindowExpressionBindingBase

Remarks

Follow the steps listed below to bind a PivotGrid field to the result of the calculation in Optimized mode.

Create an instance of the WindowExpressionBinding class.
Specify the expression, window frame and direction. The default expression is “Index()” that is the Indexwindow function.
Assign the WindowExpressionBinding instance to the PivotGridField.DataBinding property.

Example

The following code snippet illustrates the use of the Data Binding API:

C#
VB.NET

csharp

pivotGridControl.OptionsData.DataProcessingEngine = PivotDataProcessingEngine.Optimized;

PivotGridField fieldWindowExpression = new PivotGridField() {
    Area = PivotArea.DataArea,
    Caption = "Index",
    Name = "fWindowExpression"
};

fieldWindowExpression.DataBinding = new WindowExpressionBinding() {
    PartitioningCriteria = CalculationPartitioningCriteria.ColumnValueAndRowParentValue
};

pivotGridControl.Fields.Add(fieldWindowExpression);

pivotGridControl.OptionsData.DataProcessingEngine = PivotDataProcessingEngine.Optimized

            Dim fieldWindowExpression As New PivotGridField()
            fieldWindowExpression.Area = PivotArea.DataArea
            fieldWindowExpression.Caption = "Index"
            fieldWindowExpression.Name = "fWindowExpression"

            Dim theWindowExpressionBinding As New WindowExpressionBinding()
            theWindowExpressionBinding.PartitioningCriteria = CalculationPartitioningCriteria.ColumnValueAndRowParentValue
            fieldWindowExpression.DataBinding = theWindowExpressionBinding

            pivotGridControl.Fields.Add(fieldWindowExpression)
