问题描述

如何使用WPF绑定的 RelativeSource 和不同的用例?

How do I use RelativeSource with WPF bindings and what are the different use-cases?

推荐答案

如果要绑定对象上的另一个属性:

If you want to bind to another property on the object:

{Binding Path=PathToProperty, RelativeSource={RelativeSource Self}}

如果要在祖代上获取属性:

If you want to get a property on an ancestor:

{Binding Path=PathToProperty,
    RelativeSource={RelativeSource AncestorType={x:Type typeOfAncestor}}}

如果要在模板化父项上获取属性(因此可以在ControlTemplate中进行2种方式绑定)

If you want to get a property on the templated parent (so you can do 2 way bindings in a ControlTemplate)

{Binding Path=PathToProperty, RelativeSource={RelativeSource TemplatedParent}}

或更短(仅适用于OneWay绑定):

or, shorter (this only works for OneWay bindings):

{TemplateBinding Path=PathToProperty}
