Silverlight 4.0 silverlight中具有多个数据网格的ScrollViewer

我在stackpanel中有3个datagrid，我还需要在scroll viewer中添加它们。当我尝试将滚动查看器添加到网格或堆栈面板时，什么都没有发生。当我用滚动查看器环绕整个stackpanel和grid时，它可以工作，但它将滚动条放在页面的一侧，与datagrids分开。我需要的是grid/stackpanel将所有三个网格滚动到一起（我不希望每个数据网格滚动；我需要它们保持分组）。下面是我当前的代码。谢谢

                <StackPanel Margin="10,162,0,50" HorizontalAlignment="Left" Width="365">                    
                <Grid>  

                <Rectangle Fill="{StaticResource BaseColor}" 

                           Stroke="Gray"  
                           RadiusX="10" 
                           RadiusY="10" 
                           Margin="0,0,0,0" />

                <StackPanel x:Name="IdentifyResultsStackPanel" 
                        Margin="15,10,15,10" 
                        Visibility="Collapsed">

                <TextBlock Text="ELEMENTARY SCHOOL ATTENDANCE AREA:"

                           FontSize="14" 
                           FontStyle="Italic" 
                           Margin="0,0,0,5" />

                    <slData:DataGrid x:Name="IdentifyDetailsDataGrid" 
                                 AutoGenerateColumns="False"
                                 LoadingRow="IdentifyDetailsDataGrid_LoadingRow"
                                 HeadersVisibility="None" >

                    </slData:DataGrid>

                    <TextBlock Text="MIDDLE SCHOOL ATTENDANCE AREA:"

                        </slData:DataGrid.Columns>
                    </slData:DataGrid>

                    <TextBlock Text="HIGH SCHOOL ATTENDANCE AREA:"
