The following example shows how to save the pivot grid’s layout to a file in XML format. To investigate how this works, click the “Save” button, which calls the PivotGridControl.SaveLayoutToXml method. Once saved, the pivot grid’s layout can then be restored by clicking the “Load” button, which calls the PivotGridControl.RestoreLayoutFromXml method.
