DualBinding<T>

BindingReferences
public class DualBinding<T> : Binding
Binding for joining two object bindings together
Remarks: The DualBinding is the most useful binding, as it allows you to bind two objects together. This differs from the IndirectBinding<T> where it only specifies how to get/set the value from a single object.
Type parameters:
T
