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

As in the last article, we'll set the Data Context for the Window.

The third and last Text Box uses the Property Changed value, which means that the source value will be updated each time the bound property changes, which it does in this case as soon as the text changes.

Try running the example on your own machine and see how the three textboxes act completely different: The first value doesn't update before you click the button, the second value isn't updated until you leave the Text Box, while the third value updates automatically on each keystroke, text change etc.

The other options are Property Changed, Lost Focus and Explicit.

The first two has already been described, while the last one simply means that the update has to be pushed manually through to occur, using a call to Update Source on the Binding.
