As Tormod suggested, the preferable methods would be changing the collection to an ObservableCollection, or implementing INotifyCollectionChanged in the collection would take care of refreshing the UI. However, if those options aren't available, then you can 'force' a refresh by using INotifyPropertyChanged in whatever class contains the collection. We then will be treating the list just like a regular property, and using the setter to notify on changes. To do this it requires re-assigning the reference, which is why using something like an ObservableCollection is preferred, as well as raising the PropertyChanged event. Here is a quick sample showing how this can be done with just a standard generic List: <pre><code>public partial class Window1 : Window, INotifyPropertyChanged { public Window1() { InitializeComponent(); this.Names = new List<string>() { "Mike", "Robert" }; this.DataContext = this; } private IList<string> myNames; public IList<string> Names { get { return this.myNames; } set { this.myNames = value; this.NotifyPropertyChanged("Names"); } } private void OnAddName(object sender, RoutedEventArgs e) { Names.Add("Kevin"); Names = Names.ToList(); } public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(String info) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(info)); } } } </code></pre> Xaml: <pre><code><Window x:Class="Sample.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <StackPanel> <ListBox ItemsSource="{Binding Names}" /> <Button Content="Add Name" Click="OnAddName" /> </StackPanel> </Grid> </code></pre>

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.
