Normally my View Models inherit from my View Model Base base class, which provides a Raise Property Changed method and, when in debug mode, uses reflection to check if the property name is valid.

Now I’d recently refactored the code so this particular View Model wasn’t using the base class, so my first instinct was that I’d simply mistyped the property name magic string in the event – but that was all fine.

Windows Presentation Foundation (WPF) data binding provides a simple and consistent way for applications to present and interact with data.

Elements can be bound to data from a variety of data sources in the form of common language runtime (CLR) objects and XML.

If you run the program you will see that the first text box has already read the value from the source. When the control loses focus, the Text Block at the bottom of the window updates, showing that the information entered is copied back to the source.

The update trigger for a data binding determines when changes made in the control's property are passed back to the data source.

We'll use the One Time binding for the fourth Text Box.

This binding causes the text box to be initialised on loading.

They are valid only for one-way and two-way bindings.

Four options are available, each defined in the enumeration. This mode causes changes in the property of a control to be copied to the data source when the control loses focus.
