The TreeListView is designed to display information in a tree - in either bound or unbound mode. Data is arranged in columns and nodes (rows). Grid columns correspond to data fields in a data source and nodes represent data records.

• Xaml

<dxg:GridControl AutoGenerateColumns="AddNew" 
                 EnableSmartColumnsGeneration="True" 
                 ItemsSource="{Binding Customers}">
    <dxg:GridControl.View>
        <dxg:TreeListView Name="treeListView" AutoWidth="True"
                          KeyFieldName="ID" ParentFieldName="ParentID"
                          TreeDerivationMode="Selfreference"/>
    </dxg:GridControl.View>
</dxg:GridControl>
