Question

I have these classes:

public class MovieExt
{
        public string Title { get; set; }
        public string Year { get; set; }
        public List<string> Genres { get; set; }
        public List<Actor> Actors { get; set; }
        ....
}

public class Actor
{
    public string Name { get; set; }
    public string Birth { get; set; }
    public string Biography { get; set; }
    public string Url { get; set; }

}

and this is my method in my page:

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{

    object obj;
    if (PhoneApplicationService.Current.State.TryGetValue("movie", out obj))
    {
        MovieExt movie = (MovieExt)obj;
        this.DataContext = movie;
        this.imgPoster.Source = new BitmapImage(new Uri(movie.PosterUrl, UriKind.Absolute));
    }
    base.OnNavigatedTo(e);
}

and in page I am binding properties like this:

<ListBox Grid.Row="4" Grid.Column="1" 
                             Margin="5,5,5,5"
                             ItemsSource="{Binding Path=Actors }"
                             x:Name="listStars"/>

For everything it´s working (genres and others). Everything else is string. But for actors I want to bind in list name and after clicking on the actor I want to go to url. How can I bind name property from actor? Thanks

Answer 1

First of all, you need to create OnSelectedItemChanged event on your ListBox to handle clicks on your Actors.

Then you need to get your clicked item. You can do this in several ways. The simplest way is listBox.SelectedItem property.

And then your can get your Url with (listBox.SelectedItem as Actor).Url

Also, when you go back from details page, SelectedItem will be not null and click on the same item not fired event in second time. So, set SelectedItem to null when click is handled

UPD: to properly bind Actor class to ListBox you need to create ItemTemplate:

 <ListBox ...>
      <ListBox.ItemTemplate>
           <DataTemplate>
                <StackPanel>
                     <TextBlock Text={Binding Name} />
                     <TextBlock Text={Binding Birth} />
                     <TextBlock Text={Binding Biography} />
                     <TextBlock Text={Binding Url} />
                </StackPanel>
           </DataTemplate>
      </ListBox.ItemTemplate>
 </ListBox>
