    <p>neither view model or view model base are subscribing to the PropertyChanged event. So therefore, neither of these objects will receive the event notification when its raised by DIPREDIPForView.</p> <p>presumably DIPREDIPViewModel needs to subscribe to PropertyChanged on DIPREDIPForView, and the event subscription needs to point to the OnPropertyChanged event handler on BaseViewModel .</p> <p>Not sure if this is what you are looking for.</p> <p>Here is a sample...</p> <pre><code>[Test] public void TestEventIsRaised() { TestEventSubscriber subscriber = new TestEventSubscriber(); subscriber.SetFirstName("joe"); Assert.IsTrue(subscriber.EventWasHandledInTestDouble); } public class TestEventSubscriber : EventSubscriber { public bool EventWasHandledInTestDouble; public TestEventSubscriber() { } protected override void OnMyEvent(object sender, EventArgs args) { EventWasHandledInTestDouble = true; } } public class EventSubscriber { private EventRaiser eventRaiser = new EventRaiser(); public EventSubscriber() { eventRaiser.MyEvent += (sender, args) =&gt; { Console.Write("Event was handled via anonymous delegate"); }; eventRaiser.MyEvent = OnMyEvent; } public void SetFirstName(string firstName) { eventRaiser.FirstName = "bob"; } protected virtual void OnMyEvent(object sender, EventArgs args) { Console.WriteLine("Event was handled via virtual method..."); } } public class EventRaiser { public EventHandler MyEvent; public EventRaiser() { } private string firstName; public string FirstName { get { return firstName; } set { firstName = value; EventHandler handler = this.MyEvent; if (handler != null) MyEvent(this, EventArgs.Empty); } } } </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
