    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

    public class WindowExpressionBinding :
        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:

    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);
