效果如下：

鄙人虽然开发WPF有些时间，但之前一直是一些简单Template和Style改改之类的工作，并没有深入研究过。此次为了完成工作，首先也是网上搜了半天，没有找到合适的代码直接拷贝（搜索能力待提高），干脆就直接静下心来琢磨琢磨。

一开始在界面上就放了Slider，挠挠头，怎么修改Template才能达到效果呢？后来想到了Blend，之前一直听说很强大的界面设计工具，但是一直没有用过，就趁此机会就简单运用了一下。Blend中很牛逼的就是编辑模板，通过创建模板副本，可以看到Slider结构

结合代码发现，Thumb左右两边的ReapeatButton的宽度会随着Thumb的位置会变化。那问题就变得简单很多，修改左RepeatButton的Template就可以达到目的，核心代码如下。

<Style x:Key="DecreaseBtn" TargetType="{x:Type RepeatButton}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type RepeatButton}"> <Border Background="{TemplateBinding Background}" Height="{TemplateBinding Height}" Width="{TemplateBinding Width}"> <!--轨迹，设置Background--> <Border Margin="0,0,-1,0" Background="{StaticResource SliderThumb.Track.DecreaseBackground}" VerticalAlignment="center" Height="4.0" /> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style>

其实最重要的还是控件的结构，只要对此很熟悉，做出理想的控件应该不难。
