WPF C1Flexgrid 绑定主-子关系的数据

在WinForm下,可以将两个C1FlexGrid绑定到DataSet的某个表和这个表上的DataRelation上,方便地实现主-子数据的展现.
在WPF下,我采用相同的方法,但是在移动主表的选择行时,子表中的数据无法刷新,但ListBox可以,请问是何原因?
官方网站的 http://download.componentone.com/pub/Demo/WPF/FlexGrid/FlexGridXBAP.xbap例子中可以实现移动"当前行",但与其提供的下载代码不符,从下载的代码看,是把FlexGrid绑定到ObservableCollection的.请问如果绑定到DataTable或DataView如何实现移动"当前行"?
我使用的是VS2008+C1StudioWPF2011V3
这是xaml代码

1. <Window x:Class="Window1"

3.     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
   
4.     Title="Window1" Height="300" Width="300" xmlns:my="clr-namespace:C1.WPF.FlexGrid;assembly=C1.WPF.FlexGrid">
   
5.     <Grid Name="MainLayout">
   
6.         <Grid.RowDefinitions>
   
7.             <RowDefinition Height="*"/>
   
8.             <RowDefinition Height="*"/>
   
9.         </Grid.RowDefinitions>
   
10.         <Grid.ColumnDefinitions>
    
11.             <ColumnDefinition Width="*"/>
    
12.             <ColumnDefinition Width="*"/>
    
13.         </Grid.ColumnDefinitions>
    
14.         <my:C1FlexGrid Name="MainGrid" Grid.Row="0" Grid.Column="0"/>
    
15.         <my:C1FlexGrid Name="SubGrid" Grid.Row="0" Grid.Column="1"/>
    
16.         <ListBox Name="MainList" Grid.Row="1" Grid.Column="0"/>
    
17.         <ListBox Name="SubList" Grid.Row="1" Grid.Column="1"/>
    
18.     </Grid>
    
19.    
    
20. </Window>

你好，下面代码演示了在WPF中如何进行主从数据的联动
