ScrollViewer, like few other controls in WPF, have some named parts. In order to be used in correct places they need to be named properly. ScrollViewerstyling has been explained on this MSDNsite but basically it has 3 parts ScrollContentPresenter, HorizontalScrollBarand VerticalScrollBar. In turn each ScrollBarwill have its own named parts to style. And for that go to this MSDNsite. In your case you can wrap your ListBoxin ScrollViewerlike this:
ScrollViewer与 WPF 中的其他几个控件一样，有一些命名部分。为了在正确的地方使用它们，它们需要正确命名。ScrollViewer样式已在此MSDN站点上进行了解释，但基本上它包含 3 个部分ScrollContentPresenter，HorizontalScrollBar以及VerticalScrollBar. 反过来，每个ScrollBar人都有自己的命名部分来设计风格。为此，请访问此MSDN站点。在你的情况下，你可以用你ListBox在ScrollViewer这样的：
<ScrollViewer>
<ListBox/>
</ScrollViewer>
In this case you might also consider hiding original scroll bars of your ListBox. If you don't put any restriction on Heightof Listboxit will grow to fit all elements and this in turn will cause your ScrollViewerto show your custom scroll bars.
Or you can change template of your ListBoxlike this for example (MSDN):
在这种情况下，您还可以考虑隐藏ListBox. 如果您不对其施加任何限制Height，Listbox它将增长以适应所有元素，这反过来会导致您ScrollViewer显示自定义滚动条。或者您可以更改您的模板，ListBox例如（MSDN）：
<Style TargetType={x:Type ListBox}>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBox}">
<ScrollViewer x:Name="ScrollViewer">
<ItemsPresenter/>
</ScrollViewer>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
and then customize your ScrollViewerthere
然后在ScrollViewer那里定制你的
