WindowExpressionBinding Class

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

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v25.1.dll

NuGet Package: DevExpress.Win.PivotGrid

Declaration

C#

public class WindowExpressionBinding :
    WindowExpressionBindingBase

VB.NET

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.

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

Example

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

C#

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);

VB.NET

            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)
