I am having some trouble to bind my collection to my listview. I have tried a lot of different approaches from others on here for binding, and also followed [this tutorial](http://msdn.microsoft.com/en-us/library/ms748365.aspx) at first. I made it to work but it was not the way I wanted.

Anymway, here is the XML:

```
    <ListView Grid.Row="0" ItemsSource="{Binding SongList}"  SelectionMode="Extended" x:Name="ListViewMain" VerticalAlignment="Top"  ScrollViewer.VerticalScrollBarVisibility="Visible" Margin="0,1,0,0" Height="264" >
        <ListView.View>
            <GridView>
                <GridViewColumn Header="Title" DisplayMemberBinding="{Binding Title}" Width="500"/>
                <GridViewColumn Header="Artist" DisplayMemberBinding="{Binding Artist}" Width="100"/>
                <GridViewColumn Header="Album" DisplayMemberBinding="{Binding Album}" Width="100"/>
                <GridViewColumn Header="Length" DisplayMemberBinding="{Binding Length}" Width="100"/>
                <GridViewColumn Header="Location" DisplayMemberBinding="{Binding Songfile}" Width="100"/>
            </GridView>
        </ListView.View>
    </ListView>

```

In my code, to add items to my collection, I do :

```
public MainWindow()
{
     InitializeComponent();
         ...
     PlayListItem addsong = new PlayListItem(title, artist, album, length, filename);
}

```

The PlayListItem class with the ObservableCollection :

```
public class PlayListItem
{
 public ObservableCollection<Song> _SongList = new ObservableCollection<Song>();
 public ObservableCollection<Song> SongList { get { return _SongList; } }       

 public PlayListItem(string _Title, string _Artist, string _Album, string _Length, string _Filename)
{
     _SongList.Add(new Song
    {
     Title = _Title,
     Artist = _Artist,
     Album = _Album,
     Length = _Length,
     SongFile = _Filename,
    });
}

 public class Song
  {
    public string Artist { get; set; }
    public string Album { get; set; }
        public String Title { get; set; }
        public string Length { get; set; }
        public String SongFile { get; set; }
  }
}

```

I think my items are added correctly each time I call the constructor, but it does not get updated on the ListView. I do not have some errors about the binding in the Output window either.

Any ideas and help would be appreciated.

EDIT :

By adding :

```
ListViewMain.ItemsSource = addsong.SongList;

```

Right after creating a new PlayListItem seems to solve the problem, as the ListView is now printing the item.
