Passing data from listbox navigation Windows Phone - json

Question

I'm getting data to create a Listbox like a blog with JSON from a webblog, I want to pass this data when you select one item, to another simple xaml page with the information of this news(Title, content and Image). How can I get all the values for a new page with the information of the selected Item of the list?
I have this code for the listBox:
<ListBox x:Name="NewsList" Margin="0,200,0,0" ItemsSource="{Binding Items}" SelectionChanged="ListBox_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17" Width="432" Height="100">
<!--Replace rectangle with image-->
<Image x:Name="Imagen" Height="100" Width="100" Margin="12,0,9,0">
<Image.Source>
<BitmapImage UriSource="{Binding LineThree}" />
</Image.Source>
</Image>
<StackPanel Width="311">
<TextBlock x:Name="Titulo" Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" FontSize="18.667" FontFamily="Tahoma" Margin="12,0,12,6"/>
<TextBlock x:Name="Contenido" Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,0" Style="{StaticResource PhoneTextSubtleStyle}" FontSize="16"/>
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I get the values from the news here :
Items is the list where I add the values of the news(Title, content, and Image)
public void LoadData()
{
WebRequest.RegisterPrefix("http://automaticband.es/blog/", WebRequestCreator.ClientHttp);
Uri serviceUri = new Uri("http://automaticband.es/blog/?json=get_recent_post");
WebClient downloader = new WebClient();
downloader.OpenReadCompleted += new OpenReadCompletedEventHandler(downloader_OpenReadCompleted);
downloader.OpenReadAsync(serviceUri);
}
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(String propertyName)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (null != handler)
{
handler(this, new PropertyChangedEventArgs(propertyName));
}
}
void downloader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
if (e.Error == null)
{
try
{
Stream responseStream = e.Result;
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Posts));
Posts response = (Posts)ser.ReadObject(responseStream);
if (response.posts != null && response.posts.Count > 0)
{
foreach (Post post in response.posts)
{
this.Items.Add(new ItemViewModel() { LineOne = post.title, LineTwo = post.excerpt,
LineThree = post.thumbnail});
}
}
}
catch (Exception x)
{
return;
}
this.IsDataLoaded = true;
}
}
Thank you
