MovingCalculationBinding Class

Defines aggregations across a specified number of values before and/or after the current value.

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v19.2.dll

Declaration

C#

public class MovingCalculationBinding :
    MovingCalculationBindingBase

VB.NET

Public Class MovingCalculationBinding
    Inherits MovingCalculationBindingBase

Remarks

To bind a PivotGrid field to the result of the calculation, perform the following steps:

1. Create an instance of the MovingCalculationBinding class with the Source property set to the DataBindingBase descendant instance.
2. Specify the window frame and calculation settings.
3. Assign the MovingCalculationBinding instance to the PivotGridField.DataBinding property.

Example

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

Note

The complete sample project is available in the DevExpress Demo Center: Code Examples - Optimized Mode - Field Calculation Bindings module in the XtraPivotGrid MainDemo.

C#

pivotGridControl.OptionsData.DataProcessingEngine = PivotDataProcessingEngine.Optimized;

PivotGridField fieldProductAmount = new PivotGridField()
{
    Area = PivotArea.DataArea,
    Caption = "Product Sales",
    Name = "fProductAmount"
};

PivotGridField fieldProductAmountMoving = new PivotGridField()
{
    Area = PivotArea.DataArea,
    Caption = "Moving Average",
    Name = "fMovingAverage"

};
DataSourceColumnBinding productAmountBinding = new DataSourceColumnBinding("ProductAmount");
//Bind a field to a column in the data source.
fieldProductAmount.DataBinding = productAmountBinding;
//Calculate the average of the preceding, current and following values in the column.
fieldProductAmountMoving.DataBinding = new MovingCalculationBinding()
{
    Source = productAmountBinding,
    PartitioningCriteria = CalculationPartitioningCriteria.ColumnValue,
    SummaryType = PivotSummaryType.Average,
    PreviousValuesCount = 1,
    NextValuesCount = 1
};
pivotGridControl.Fields.AddRange(new PivotGridField[] {
    fieldProductAmount,
    fieldProductAmountMoving
});

VB.NET

pivotGridControl.OptionsData.DataProcessingEngine = PivotDataProcessingEngine.Optimized

Dim fieldProductAmount As New PivotGridField()
fieldProductAmount.Area = PivotArea.DataArea
fieldProductAmount.Caption = "Product Sales"
fieldProductAmount.Name = "fProductAmount"

Dim fieldProductAmountMoving As New PivotGridField()
fieldProductAmountMoving.Area = PivotArea.DataArea
fieldProductAmountMoving.Caption = "Moving Average"
fieldProductAmountMoving.Name = "fMovingAverage"

Dim productAmountBinding As New DataSourceColumnBinding("ProductAmount")
'Bind a field to a column in the data source.
fieldProductAmount.DataBinding = productAmountBinding
'Calculate the average of the preceding, current and following values in the column.
Dim theMovingCalculationBinding As New MovingCalculationBinding()
theMovingCalculationBinding.Source = productAmountBinding
theMovingCalculationBinding.PartitioningCriteria = CalculationPartitioningCriteria.ColumnValue
theMovingCalculationBinding.SummaryType = PivotSummaryType.Average
theMovingCalculationBinding.PreviousValuesCount = 1
theMovingCalculationBinding.NextValuesCount = 1
fieldProductAmountMoving.DataBinding = theMovingCalculationBinding

pivotGridControl.Fields.AddRange(New PivotGridField() { fieldProductAmount, fieldProductAmountMoving})
