How to style the slider control in WPF?
提问by Sander Versluys
回答by Rhys
The Slider Control has many parts Thumb, RepeatButtons and a Track. It is one of those controls that have named elements, like PART_Track, referenced by the code-behind for it to work correctly. A good starting point is to use Blend to help you out.
Slider Control 有很多部分 Thumb、RepeatButtons 和 Track。它是具有命名元素（如 PART_Track）的控件之一，由代码隐藏引用以使其正常工作。一个好的起点是使用 Blend 来帮助您。
Start a new project (or create a new window). In the XAML window add the following:
开始一个新项目（或创建一个新窗口）。在 XAML 窗口中添加以下内容：
<ScrollBar/>
Then in design window of Blend right-click on the control and select "Edit control parts (Template)\Edit a Copy...". This will reverse engineer the standard control template. This can then be edited.
然后在 Blend 的设计窗口中右键单击控件并选择“编辑控件部件（模板）\编辑副本...”。这将对标准控制模板进行逆向工程。然后可以对其进行编辑。
The Blend output is this:-
混合输出是这样的：-

The namespace used for this was this (add to top of file):-
用于此的命名空间是这样的（添加到文件顶部）：-
xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Luna"
You can then obviously alter the generated style to your heart's content
然后，您显然可以根据自己的喜好更改生成的样式
You would need to either programmatically find the scrollbar embedded in the control or apply the style to all scrollbars in the scope by altering the style definition, so:-
您需要以编程方式找到嵌入在控件中的滚动条，或者通过更改样式定义将样式应用于范围内的所有滚动条，因此：-
<Style x:Key="ScrollBarStyle1" TargetType="{x:Type ScrollBar}">
...
</Style>
becomes
变成
<Style TargetType="{x:Type ScrollBar}">
...
</Style>
So that it will be applied to all scroll bars in the region defined by the style.
这样它将应用于样式定义的区域中的所有滚动条。

You will have to create a control template to restyle the part of the control you want.
您必须创建一个控件模板来重新设置所需控件部分的样式。
Have a look at this MSDN articleand thisarticle which should help you.

A nice MSDN article giving control templates for all the WPF controls is available here:

Bear in mind that these control templates generate the same control visually (i.e.: these are the control templates that WPF uses). But it's a good starting point for customizing your controls' Visual Trees.
请记住，这些控件模板在视觉上生成相同的控件（即：这些是 WPF 使用的控件模板）。但这是自定义控件的可视化树的一个很好的起点。

Here's a simple and quick way:
这是一个简单快捷的方法：
<Slider ...>
<Slider.LayoutTransform>
<ScaleTransform CenterX="0" CenterY="0" ScaleX="1" ScaleY="0.5"/>
</Slider.LayoutTransform>
</Slider>
This is not EXACTLY 8 pixels but you can play a bit with the ScaleY property until you get the size you want.
这不是恰好 8 个像素，但您可以使用 ScaleY 属性进行一些调整，直到获得所需的大小。

Just a proof of concept that you can also style single parts of composite controls like the Slider: But beware, the choice of colors was rather random, so this is gonna be ugly. Unfortunately, the Thumb-Style does not have an effect if you leave out the custom style for the slider.
只是一个概念证明，您还可以设置像 Slider 这样的复合控件的单个部分的样式：但要注意，颜色的选择是相当随机的，所以这会很难看。不幸的是，如果您忽略滑块的自定义样式，Thumb-Style 将不起作用。
