You can see that the bindings are connecting correctly because all three key controls contain names on loading.

However, if you modify the first or last names, the full name text block does not change.

Instead, the source was updated only after focus was lost on the Text Box.

The problem here does not lie with the Full Name property.

If you were to call it you would see the correct, updated full name.

In the earlier article we used simple bindings to display string and integer values that were controlled directly by the controls in a window.

When controls update a property that is also the direct source of other bindings, the user interface can update automatically.
