Help on ItemsControl Expander manipulation

Hi,

I'm using Silverlight 4 and VS 2010.

I have a StackPanel with a ItemsControl.
It's ItemTemplate is binded to it's respective DataTemplate.
It is filled with a few Expanders with a lot of data in each one.
Whenever I expand one of these Expanders I want to collapse all the remaining Expanders.

On another part of my project I have a similar structure where the Expanders are hard coded.
To achieve the same result I just go through the StackPanel.Children collection with a foreach cicle and collapse all the Expanders.

Using a Stackpanel and an ItemsControl I can't do that because the Itemscontrol is the only child on the Stackpanel.Children.

Can anyone help on how do I get to each of the Expanders using c# code behind and collapse them?

<DataTemplate x:Key="AvaliacaoDataTemplate">
   <Grid>
      <toolkit:Expander x:Name="ExpanderAvaliacao" Header="{Binding}" d:LayoutOverrides="Width, Height" HeaderTemplate="{StaticResource AvaliacaoDataTemplateHeader}" Style="{StaticResource StyleExpanderBlue3}" Expanded="Expander_Expanded">
         <StackPanel>
            <!-- Lots of stuff -->
         </StackPanel>
      </toolkit:Expander>
   </Grid>
</DataTemplate>


<StackPanel x:Name="Avaliacoes">
   <ItemsControl x:Name="ItemsAvaliacao" ItemTemplate="{StaticResource AvaliacaoDataTemplate}"/>
</StackPanel>

I really need some light on this issue!
Anyone?!!


Thanks.
