Gets or sets a value that indicates whether to include the DataErrorValidationRule. Gets or sets a value that indicates whether to include the ExceptionValidationRule. Gets the collection of ValidationRule objects for this instance of MultiBinding. Gets the Type of the current instance. Creates a shallow copy of the current Object. Returns an object that should be set on the property where this binding and extension are applied. Indicates whether the Bindings property should be persisted.

Provides MultiBinding functionality for Windows 8. This portable library is available as NuGet package for Windows 8.
NOTE: As these packages are obsolete, they are no longer supported. So, you should better install portable library version described above for use in your Windows 8. This library provides you MultiBindingHelper. MultiBindings attached property which you should initialize with a MultiBindingCollection instance which you should populate with MultiBinding items. Instance of MultiBinding class hosts Binding items.
TemplatedParent and RelativeSouce. None are not yet supported. PropertyChanged is set by default. To update source explicitly use GetMultiBindingExpression extension method.
As you can see, you do not set directly MultinBinding instance to target property, but use attached property instead. If the user does the same for "Last Name" field,it will be reflected in the "Complete Name" field's last name part The reverse should also be true.
Let us write a class file "CustomMultiValueConvertor. In the "Convert" function, values[0] is the first name while values[1] is the last name. We are concatenating the first and second values and delimiting them with spaces. The "Path" property defines the actual property from which to get the data which is "Text" here. Multibinding needs a multivalue convertor to work properly.
If we just omit it and write the below code. We are using the UpdateSourceTrigger that notifies as soon as the source updates. The value is set to "PropertyChanged" default property which states that whenever anything is updated in the control the bound element will reflect the same.
Finally let us run the application.
