    Title="Window1" Height="276" Width="483" xmlns:my="clr-namespace:Infragistics.Windows.DataPresenter;assembly=Infragistics3.Wpf.DataPresenter.v8.1.Express">
    <Grid>
        <Grid.Resources>
            <!-- Creates a DataSet with
         two related DataTables. -->
            <ObjectDataProvider
                  x:Key="dataSetProvider"
                  MethodName="CreateDataSet"
                  ObjectType="{x:Type local:DataSetCreator}"
                  />
        </Grid.Resources>
        <my:XamDataGrid x:Name="XamDataGrid1"

        </my:XamDataGrid>
    </Grid>
</Window>

using System;
using System.Data;

namespace Wpf2
{
    public static class DataSetCreator
    {
        public static DataSet CreateDataSet()
        {
            DataSet ds = new DataSet();

            // Create the parent table.
            // ***************************************
            DataTable tbl = new DataTable( "Master" );
            tbl.Columns.Add( "ID", typeof( int ) );
            tbl.Columns.Add( "Name" );
            for( int i = 0; i < 3; ++i )
            {
                DataRow row = tbl.NewRow();
                row["ID"] = i;
                row["Name"] = "Master #" + i;
                tbl.Rows.Add( row );
            }
            ds.Tables.Add( tbl );

            // Create the child table.

            {
                DataRow row = tbl.NewRow();
                row["MasterID"] = i % 3;
                row["Info"] = String.Format(
                    "Detail Info #{0} for Master #{1}",
                    (i / 3), (i % 3) );
                tbl.Rows.Add( row );
            }
            ds.Tables.Add( tbl );

            // Associate the tables.

            ds.Relations.Add(
