这篇文章主要介绍了WPF Slider滑动条的颜色修改方法,需要的朋友可以参考下

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。
