The following example demonstrates how to add Person data to a custom ObservableCollection of Person objects. 

XAML
Copy Code 
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"
      xmlns:local="clr-namespace:Xceed.Wpf.Documentation"

   </local:PersonObservableCollection>
   <xcdg:DataGridCollectionViewSource x:Key="cvs_person"
                                      ItemType="{x:Type local:Person}"

      <xcdg:DataGridCollectionViewSource.SortDescriptions>
        <scm:SortDescription PropertyName="Occupation"
                              Direction="Ascending"/>
      </xcdg:DataGridCollectionViewSource.SortDescriptions>
    </xcdg:DataGridCollectionViewSource>
  </Grid.Resources>
 <xcdg:DataGridControl x:Name="PersonGrid"
                       ItemsSource="{Binding Source={StaticResource cvs_person}}"/>
</Grid>
VB.NET
Copy Code 
Dim people As New ObservableCollection( Of Person )()

Dim collectionView As New DataGridCollectionView( people, GetType( Person ) )
dataGridControl.ItemsSource = collectionView
C#
Copy Code 
ObservableCollection<Person> people = new ObservableCollection<Person>();
