PivotSerializationOptions Class

Contains options that control how the PivotGridControl’s layout is saved to and restored from a data store (an XML file or stream).

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v23.2.dll

NuGet Package: DevExpress.Wpf.PivotGrid

Declaration

C#

public class PivotSerializationOptions

VB.NET

Public Class PivotSerializationOptions

Remarks

To save the layout, use the PivotGridControl.SaveLayoutToStream or PivotGridControl.SaveLayoutToXml method. To load the layout, use the PivotGridControl.RestoreLayoutFromStream or PivotGridControl.RestoreLayoutFromXml method.

To learn more, see Save and Restore Layout.

Note

To correctly save and restore the pivot grid’s layout, its fields should be uniquely identified using the Name attribute.

Example

This example shows how to save (or restore) the PivotGridControl‘s data and layout to a file. To correctly restore fields if the pivot grid’s PivotGridControl.Fields collection is empty, the PivotSerializationOptions.RemoveOldFields property should be set to false.
