Question

Hi all i seem to be stuck with this, i can get it display the first item in the array but not the whole list

 var actor = xmlInfo
         .Descendants("person")
            .Where(x => x.Attribute("job").Value == "Actor")
            .Select(x => x.Attribute("name").Value)
         .ToArray();

my listbox is the following

 ThirdListBox.ItemsSource = from info in xmlInfo.Descendants("movies")
                                   select new MovieInfo

                                   {
                                       tagline = info.Element("movie").Element("tagline").Value,
                                       castDirector = director[0],
                                       castActor = actor[0],
                                   };

xaml is

<ListBox Name="ThirdListBox" Margin="0,-24,-12,0" ItemsSource="{Binding Items}">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Margin="0,0,-12,0" Width="432" Height="800"  Background="#82101010">
                           <TextBlock Text="{Binding tagline}" TextWrapping="Wrap" FontSize="30" DataContext="{Binding}" />
                            <TextBlock Text="{Binding castDirector}" TextWrapping="Wrap" FontSize="30" DataContext="{Binding}" />
                            <TextBlock Text="{Binding castActor}" TextWrapping="Wrap" FontSize="30" DataContext="{Binding}" />
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>

Answer 1

So, I think based on what you’ve said, you’re going to have to change a few things. First off, if you want to display a list of lists, you’re not going to be able to do it by binding to textboxes. Here’s a way to set it up. I know this isn’t exactly what you’re asking, but it might get you in the right direction.

A couple caveats:

1. Don’t use a ListBox unless you need a ListBox. ItemsControl works great if you don’t need to select an item from the list.

2. I’m not 100% sure what you’re trying to get, so this is my best guess at what you ultimately want to see. If it isn’t quite there, let me know, and I’ll see if I can tweak it some more.

In your DataContext’s class (e.g. ViewModel):

    public ObservableCollection<Movie> Items { get; set; }

    public MainViewModel()
    {
        XDocument xmlInfo = XDocument.Load(@"c:\temp\Xmlfile1.xml");


        var items = xmlInfo.Descendants("movie")
                        .Select(x => new Movie
                                         {
                                             MovieName = x.Element("name").Value, 
                                             Actors = x.Descendants("person").Where(p => p.Attribute("job").Value == "Actor").Select(a=>a.Attribute("name").Value).ToList(),
                                             Directors = x.Descendants("person").Where(p => p.Attribute("job").Value == "Director").Select(a => a.Attribute("name").Value).ToList()
                                         });

        Items = new ObservableCollection<Movie>(items);



    }

Movie is defined as:

public class Movie
{
    public string MovieName { get; set; }
    public List<string> Actors { get; set; }
    public List<string> Directors { get; set; }

}

Then, the XAML is defined as:

    <ListBox ItemsSource="{Binding Items}">

        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                    <TextBlock Text="{Binding MovieName}" FontSize="32"/>
                    <StackPanel Orientation="Horizontal">
                        <ListBox ItemsSource="{Binding Actors}" Margin="5"/>
                        <ListBox ItemsSource="{Binding Directors}" Margin="5"/>
                    </StackPanel>
                </StackPanel>

            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

Which yields:
