Getting information from child element of stackpanel within listbox - windows-phone-7

Question

I know there should be a simple solution to this question but I just cant seem to figure it out here is what my code looks like:
<ListBox HorizontalAlignment="Left"
x:Name="locationsNB"
VerticalAlignment="Top"
Height="563"
Width="455"
SelectionChanged="locationsNB_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal"
Margin="18,0,0,0"
x:Name="placeDetails">
<Image Source="{Binding icon}"
Height="40"
Width="40"
VerticalAlignment="Top"
Margin="0,10,8,0" />
<StackPanel Width="350">
<TextBlock Text="{Binding name}"
FontSize="35"
Foreground="#399B81"
TextWrapping="Wrap" />
<TextBlock Text="{Binding vicinity}"
FontSize="20"
Foreground="#888888"
TextWrapping="Wrap" />
<TextBlock x:Name="reference"
Text="{Binding reference}"
Visibility="Collapsed" />
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I want to get the stackpanel->reference text (Text="{Binding reference}") of the selected item I dont know what my C# should look like but any help will be greatly appreciated.

If the ItemsSource of your ListBox is bound to a collection of items then you can use the SelectedItem property of the ListBox
private void locationsNB_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var listbox = (ListBox)sender;
var myObject = listbox.SelectedItem as MyCustomObject;
if (myObject == null) return;
// perform your custom logic with this item
}
