[SerializableAttribute] 
public sealed class BindableInstanceDependencyProperty : InstanceDependencyProperty

Remarks

A BindableInstanceDependencyProperty is associated with a DependencyProperty that stores its value and allows binding.

A BindableInstanceDependencyProperty combines an InstanceDependencyProperty ability to persist a property value across clones with a DependencyProperty ability to use ActivityBind to retrieve the value of the property from somewhere else at run time.

Because binding is pull-based, any variable can supply the value for the bind, but the side of the binding that accepts the value must be a DependencyProperty. This is because a DependencyProperty contains the requisite information about how and where to get the value when it is needed.

The following table provides guidance about when to use a DependencyProperty, an InstanceDependencyProperty, a BindableInstanceDependencyProperty, or an ordinary member variable.

If you need	Use this type of variable
Binding, but not persistence	DependencyProperty
Persistence, but not binding	InstanceDependencyProperty
Binding and persistence	BindableInstanceDependencyProperty
Neither binding nor persistence	Ordinary member variable
