    <p>So I'm trying to create my own music player. I have a Listview updating properly with current playlist. My problem begins when I want a grid to show the song which is currently playing. When binding to those strings they all return <code>Null</code>.</p> <p>From Class:</p> <pre><code>public class Song : INotifyPropertyChanged { public string Title { get; set; } public string Path { get; set; } public string Artist { get; set; } public int Time { get; set; } public string Album { get; set; } //public ImageBrush Portrait { get; set; } public event PropertyChangedEventHandler PropertyChanged; public Song(string title, string path, string artist, int time, string album)//, ImageBrush portrait) { this.Path = path; this.Title = title; this.Artist = artist; this.Time = time; this.Album = album; //this.Portrait = portrait; } public string SongCurrentPlaying { get { return Title; } set { Title = value; OnPropertyChanged("SongCurrentPlaying"); } } protected void OnPropertyChanged(string name) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) { handler(this, new PropertyChangedEventArgs(Title)); } } </code></pre> <p>From XAML:</p> <pre><code> &lt;Grid HorizontalAlignment="Left" Height="143" VerticalAlignment="Top" Width="276"&gt; &lt;Image HorizontalAlignment="Left" Height="124" Margin="10,10,0,0" VerticalAlignment="Top" Width="134" Stretch="Fill"/&gt; &lt;TextBlock HorizontalAlignment="Left" Margin="144,100,0,0" TextWrapping="Wrap" Text="{Binding Songs.Title}" VerticalAlignment="Top" Height="25" Width="122"/&gt; &lt;TextBlock HorizontalAlignment="Left" Margin="144,40,0,0" TextWrapping="Wrap" Text="{Binding SongCurrentPlaying.Title, PresentationTraceSources.TraceLevel=High}" VerticalAlignment="Top" Height="25" Width="122"/&gt; &lt;TextBlock HorizontalAlignment="Left" Margin="144,70,0,0" TextWrapping="Wrap" Text="{Binding Song.Title}" VerticalAlignment="Top" Height="25" Width="122"/&gt; &lt;TextBlock HorizontalAlignment="Left" Margin="144,10,0,0" TextWrapping="Wrap" Text="{Binding Songs.Title}" VerticalAlignment="Top" Height="25" Width="122"/&gt; &lt;/Grid&gt; </code></pre> <p>As you can see I've been experimenting on different bindings to get values from Title as example, none has been successful. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
