在WPF中设计具有样式的垂直滚动条

Question

这可能很容易做，也可能很困难，但是任何人都可以告诉我如何设计scrollviewer像这样的图像

在设计领域，我对 WPF 还很陌生。我在 Visual studio Blend 2013 中了解了这个设计，并且喜欢这个 UI 的外观和感觉，请建议一种在 xaml 或 UI 后面的代码中为其编码的方法。

这是我的拇指方法

<Style x:Key="ScrollThumbs" TargetType="{x:Type Thumb}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Thumb}">
                <Grid x:Name="Grid">
                    <Rectangle HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" Fill="Transparent" />
                    <Border x:Name="Rectangle1" CornerRadius="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto"  Background="LightGray" />
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="Tag" Value="Horizontal">
                        <Setter TargetName="Rectangle1" Property="Width" Value="Auto" />
                        <Setter TargetName="Rectangle1" Property="Height" Value="7" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

但是如何更改上下箭头。

我可以为您提供我最近在一个示例项目中合并的滚动条的示例，但我不想将拇指放在其中。因此，您可能需要调整一些示例。

这是风格：

<Style x:Key="ScrollThumbs" TargetType="{x:Type Thumb}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Thumb}">
                <Grid x:Name="Grid">
                    <Rectangle
                        Width="Auto"
                        Height="Auto"
                        HorizontalAlignment="Stretch"
                        VerticalAlignment="Stretch"
                        Fill="Transparent" />
                    <Border
                        x:Name="ScrollBarRectangle"
                        Width="Auto"
                        Height="Auto"
                        HorizontalAlignment="Stretch"
                        VerticalAlignment="Stretch"
                        Background="{TemplateBinding Background}"
