public class WindowExpressionBinding :


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.


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
