Is there anyway to access this textblock?

Question

I want to access the text content after binding of the "GameName" textblock that is inside the listbox.

        <controls:PanoramaItem Header="games" Margin="0" Height="800" Foreground="White" VerticalAlignment="Center">
            <!--Double line list with text wrapping-->
            <ListBox x:Name="GamesListBox" Margin="0,0,-12,66"  Height="614" ItemsSource="{Binding dataFeed}" SelectionChanged="GamesListBox_SelectionChanged">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal" Margin="0,0,0,17">
                            <!--Replace rectangle with image-->
                            <Image Height="100" Width="100"  Source="{Binding AllGamesImage}" Margin="12,0,9,0" VerticalAlignment="Top" HorizontalAlignment="Left" Stretch="UniformToFill" />
                            <StackPanel Width="311">
                                <TextBlock x:Name="GameName" Text="{Binding AllGamesTitle}" TextWrapping="Wrap" Foreground="White" Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="0,0,0,1"/>
                                <TextBlock Text="{Binding AllGamesDescription}" TextWrapping="Wrap" Margin="0,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
                            </StackPanel>
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </controls:PanoramaItem>

i want to take whatever is set as the text content and pass it to another page as a parameter or anything.

code behind after Shawn Kendrot suggestion.

    private void GamesListBox_SelectionChanged(object sender, EventArgs e)
    {
        var myObject = GamesListBox.SelectedItem as NewGamesClass;
        string gameName = myObject.TitleCode;

        NavigationService.Navigate(new Uri("/Pages/AchivementListPage.xaml?gameName=" + gameName, UriKind.Relative));
    }

i get a NullExeception when returing to the page here:

string gameName = myObject.TitleCode;

Answer 1

Why access the Text property when you can access the property of the object?

void GamesListBox_SelectionChanged(object sender, EventArgs e)
{
    var myObject = GamesListBox.SelectedItem as MyObject;
    string gameName = myObject.AllGamesTitle;
    // Do something with gameName
}
