In WPF, what is a TemplatedParent?
提问by David Smith
I'm trying to understand RelativeSource binding but I can't find a definition for TemplatedParent. MSDN says:
我正在尝试了解 RelativeSource 绑定，但找不到 TemplatedParent 的定义。 MSDN 说：
"Gets a static value that is used to return a RelativeSource constructed for the TemplatedParent mode."
“获取一个静态值，用于返回为 TemplatedParent 模式构造的 RelativeSource。”
It doesn't appear in the index of "Windows Presentation Foundation Unleashed".
它没有出现在“Windows Presentation Foundation Unleashed”的索引中。
Simply, what is a TemplatedParent please?

TemplatedParentrefers to the Controlinstance that the template is being applied to. You can use TemplatedParentto bind to properties declared on that object (and its base classes).
TemplatedParent指Control应用模板的实例。您可以使用TemplatedParent绑定到在该对象（及其基类）上声明的属性。

In WPF, a template is what it uses to construct the tree of a type. WPF essentially makes a copy of the template when a new object of that type is created.
在 WPF 中，模板是用来构造类型树的。WPF 本质上是在创建该类型的新对象时制作模板的副本。
As a result, insidethe template, if you want to refer to the new object, you use TemplatedParentfor quick access. Otherwise, you'll have to use RelativeSourceto walk the tree upwards to find the parent object.
因此，在模板内部，如果要引用新对象，则使用TemplatedParent快速访问。否则，您将不得不使用RelativeSource向上走树来找到父对象。

Notice:
注意：
TemplatedParent means Parent is Templated. Templated is passive voice in English. In other words, the parent element is applied with a Template. So in the template you can binding the parent's property easily.
TemplatedParent 表示 Parent 是模板化的。Templated 是英语中的被动语态。换句话说，父元素与模板一起应用。因此在模板中您可以轻松绑定父级的属性。
