Remarks

The Binding class is the high-level class for the declaration of a binding. The BindingExpression class is the underlying object that maintains the connection between the binding source and the binding target. A Binding contains all the information that can be shared across several BindingExpression objects. A BindingExpression is an instance expression that cannot be shared and that contains all the instance information about the Binding.

You can obtain a BindingExpression object by calling the GetBindingExpression method on an object, specifying the dependency property that has the binding.

Properties

DataItem	Gets the binding source object that this BindingExpression uses.
ParentBinding	Gets the Binding object of this BindingExpression.

Methods

UpdateSource()

Sends the current binding target value to the binding source property in TwoWay bindings.
