<p>I found a specific solution for extending the ObservableCollection class to one that monitors changes in the properties of the objects it contains <a href="https://stackoverflow.com/questions/269073/observablecollection-that-also-monitors-changes-on-the-elements-in-collection">here</a>.</p> <p>Here's that code with a few modifications by me:</p> <pre><code>namespace Solution { public class ObservableCollectionEx<T> : ObservableCollection<T> where T : INotifyPropertyChanged { protected override void OnCollectionChanged(NotifyCollectionChangedEventArgs e) { if (e != null) // There's been an addition or removal of items from the Collection { Unsubscribe(e.OldItems); Subscribe(e.NewItems); base.OnCollectionChanged(e); } else { // Just a property has changed, so reset the Collection. base.OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset)); } } protected override void ClearItems() { foreach (T element in this) element.PropertyChanged -= ContainedElementChanged; base.ClearItems(); } private void Subscribe(IList iList) { if (iList != null) { foreach (T element in iList) element.PropertyChanged += ContainedElementChanged; } } private void Unsubscribe(IList iList) { if (iList != null) { foreach (T element in iList) element.PropertyChanged -= ContainedElementChanged; } } private void ContainedElementChanged(object sender, PropertyChangedEventArgs e) { OnPropertyChanged(e); // Tell the Collection that the property has changed this.OnCollectionChanged(null); } } } </code></pre>

Guidance

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.
