如果您想访问 ScrollViewer 的 ScrollContentPresenter，您可以使用ControlTemplate

<ScrollViewer Style="{StaticResource LeftScrollViewer}"/>



<Style x:Key="LeftScrollViewer" TargetType="{x:Type ScrollViewer}">
 <Setter Property="OverridesDefaultStyle" Value="True"/>
 <Setter Property="Template">
 <Setter.Value>
  <ControlTemplate TargetType="{x:Type ScrollViewer}">
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition/>
      </Grid.ColumnDefinitions>
      <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
      </Grid.RowDefinitions>

      <ScrollContentPresenter Grid.Column="1"/>

      <ScrollBar Name="PART_VerticalScrollBar"
        Value="{TemplateBinding VerticalOffset}"
        Maximum="{TemplateBinding ScrollableHeight}"
        ViewportSize="{TemplateBinding ViewportHeight}"
        Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}"/>
      <ScrollBar Name="PART_HorizontalScrollBar"
        Orientation="Horizontal"
        Grid.Row="1"
        Grid.Column="1"
        Value="{TemplateBinding HorizontalOffset}"
        Maximum="{TemplateBinding ScrollableWidth}"
        ViewportSize="{TemplateBinding ViewportWidth}"
        Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"/>

    </Grid>
   </ControlTemplate>
  </Setter.Value>
 </Setter>
</Style>

与其尝试从 ScrollViewer 向下走，也许您想从 Content up绑定一些东西？

就像是：

<Grid Width={Binding Path=ActualWidth RelativeBinding={RelativeBinding FindAncestor, AncestorType={x:Type ScrollContentPresenter}}}>

注意：该语法可能不是 100% 正确的，它不在我的脑海中
