How to Extract Default Control Template In Visual Studio?
提问by foreyez
I'm wondering how I can extract (get a copy) of the Default Template of a given control using Visual Studio. I know this can be done with Expression Blend (right click a control, "Edit Template" -> "Edit a Copy...") which then copies the default control template in my Xaml. But can this be done with Visual Studio at all?
我想知道如何使用 Visual Studio 提取（获取副本）给定控件的默认模板。我知道这可以通过 Expression Blend 完成（右键单击一个控件，“编辑模板”->“编辑副本...”），然后将默认控件模板复制到我的 Xaml 中。但是这完全可以用 Visual Studio 来完成吗？

From Visual studio - right click the control, choose properties,
从 Visual Studio - 右键单击控件，选择属性，
In the properties window look for the Template Property and right click it, choose Extract Value To Resource
在属性窗口中查找模板属性并右键单击它，选择将值提取到资源
That will create a copy of the template in the XAML for you to work on.
这将在 XAML 中创建模板的副本供您处理。

Just to update this question, in VS 11 the XAML designer allows you to do this just like Expression Blend.
只是为了更新这个问题，在 VS 11 中，XAML 设计器允许您像 Expression Blend 一样执行此操作。

As far as I know it's not possible. However, you can use Show Me The Templateto view the default template for a given control.
据我所知这是不可能的。但是，您可以使用Show Me The Template查看给定控件的默认模板。

One thing to keep in mind: if you already have a style defined somewhere that targets the given control then all of the above described options will be disabled. I had the following bit of code in my App.xaml file:
要记住的一件事：如果您已经在某处定义了一个针对给定控件的样式，那么上述所有选项都将被禁用。我的 App.xaml 文件中有以下代码：
<Application.Resources>
<Style TargetType="Button">
<Setter Property="IsTabStop" Value="False"/>
</Style>
</Application.Resources>
I was pulling my hair out trying to figure out why the edit a copy...and convert to new resource...options described in the other answers were disabled for my Button (which was defined in a completely different file). I commented out the above style code for Button and suddenly both options weren't disabled anymore.
我正在努力弄清楚为什么我的 Button（在一个完全不同的文件中定义）禁用了其他答案中描述的edit a copy...和convert to new resource...选项。我注释掉了 Button 的上述样式代码，突然这两个选项都不再禁用了。
Moral of the story: VS won't generate a style containing a template copy for you if a style already exists for that element anywhere in your code.
故事寓意：如果代码中任何位置的元素已经存在样式，VS 将不会为您生成包含模板副本的样式。
