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

推荐答案

如果您要绑定的对象上的其他属性：

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

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

如果你想获得一个属性的祖先：

If you want to get a property on an ancestor:

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

如果你想获得对模板化父属性（这样你就可以在一个控件模板做双向绑定）

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}}

或短（这仅适用于单向绑定）：

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

{TemplateBinding Path=PathToProperty}
