As in the last article, we'll set the Data Context for the Window.The value will be inherited by the key Text Boxes and Text Block.The second Text Box uses the Lost Focus value, which is actually the default for a Text binding.It means that the source value will be updated each time the destination control loses focus.As the Slider was manipulated, the Text Block showed the changing value.

In the previous instalment in this tutorial we looked at the Data Context property of WPF controls.When an action happens that causes a property to change that would not normally cause an update in the WPF controls bound to it, you raise the event and name the modified property. Once ready replace the XAML of the main window with the code below: property that combines the first and last names into a single string.The final task for the first example is to set up the Data Context for the controls.For that reason, I have added a button next to the Text Box, which will update the source value on demand.In the Code-behind, you will find the Click handler, where we use a couple of lines of code to get the binding from the destination control and then call the Update Source() method on it.
