The following example shows how to save the Pivot Grid’s layout to a file in XML format. The “Save” button calls the PivotGridControl.SaveLayoutToXml method. The “Load” button calls the PivotGridControl.RestoreLayoutFromXml method to restore the saved layout.

MainWindow.xaml.cs

using System.Data;
using System.Data.OleDb;
using System.Windows;
using DevExpress.Xpf.PivotGrid;
using HowToBindToMDB.NwindDataSetTableAdapters;

namespace HowToBindToMDB {
    public partial class MainWindow : Window {
        NwindDataSet.SalesPersonDataTable salesPersonDataTable = new NwindDataSet.SalesPersonDataTable();
        SalesPersonTableAdapter salesPersonDataAdapter = new SalesPersonTableAdapter();
        public MainWindow() {
            InitializeComponent();
            pivotGridControl1.DataSource = salesPersonDataTable;
        }
        private void Window_Loaded(object sender, RoutedEventArgs e) {
            salesPersonDataAdapter.Fill(salesPersonDataTable);
        }
        private void buttonSave_Click(object sender, RoutedEventArgs e) {
            pivotGridControl1.SaveLayoutToXml("layout.xml");
        }
        private void buttonLoad_Click(object sender, RoutedEventArgs e) {
            pivotGridControl1.RestoreLayoutFromXml("layout.xml");
        }
    }
}

MainWindow.xaml.vb

    Public Partial Class MainWindow

        Private salesPersonDataTable As NwindDataSet.SalesPersonDataTable = New NwindDataSet.SalesPersonDataTable()

        Private salesPersonDataAdapter As SalesPersonTableAdapter = New SalesPersonTableAdapter()

        Public Sub New()
            Me.InitializeComponent()
            Me.pivotGridControl1.DataSource = salesPersonDataTable
        End Sub

        Private Sub Window_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
            salesPersonDataAdapter.Fill(salesPersonDataTable)
        End Sub

        Private Sub buttonSave_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
            Me.pivotGridControl1.SaveLayoutToXml("layout.xml")
        End Sub

        Private Sub buttonLoad_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
            Me.pivotGridControl1.RestoreLayoutFromXml("layout.xml")
        End Sub
