WindowExpressionBinding Class

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

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v20.1.dll

Declaration

public class WindowExpressionBinding :
    WindowExpressionBindingBase
Public Class WindowExpressionBinding
    Inherits WindowExpressionBindingBase

Remarks

To bind a PivotGrid field to the result of the calculation, follow the steps listed below.

  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:

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);
