CanContentScroll使horizo​​ntaloffset非常大

Question

我的应用中有以下滚动查看器。

<ScrollContentPresenter Grid.Row="0" Grid.RowSpan="1" Grid.Column="0" Grid.ColumnSpan="1"
                                           CanHorizontallyScroll="False" CanVerticallyScroll="False" CanContentScroll="True"
                                          Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"  OpacityMask="{x:Null}" 
                                          ScrollViewer.VerticalScrollBarVisibility="Disabled" />




 <s:SurfaceScrollBar x:Name="PART_HorizontalScrollBar" Grid.Row="1" Height="Auto" MinWidth="30"
                                    MinHeight="30" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" HorizontalContentAlignment="Stretch"
                                    VerticalContentAlignment="Stretch" AutomationProperties.AutomationId="HorizontalScrollBar" Foreground="{x:Null}"
                                    LargeChange="1" Maximum="{TemplateBinding ScrollableWidth}" Minimum="0" Opacity="0" Orientation="Horizontal" 
                                    ScrollViewer.HorizontalScrollBarVisibility="Disabled" ViewportSize="{TemplateBinding ViewportWidth}" 
                                    Visibility="Visible"
                                    Value="{Binding HorizontalOffset,
                                                                Mode=OneWay,
                                                                RelativeSource={RelativeSource TemplatedParent}}" />

问题在于，当我设置CanContentControl = True时，滚动变得太快而无法让用户处理，这是因为即使单次轻弹也会导致水平偏移太大，任何机会我如何控制我的水平偏移没有编写IScrollInfo接口？

添加详细信息：此滚动查看器用于surfacelistbox，如下所示

<ControlTemplate x:Key="SurfaceListBoxHorizontalTemplate" TargetType="{x:Type s:SurfaceListBox}">
    <s:SurfaceScrollViewer Background="{TemplateBinding Background}"
                           HorizontalScrollBarVisibility="Hidden"
                           Style="{StaticResource HorizontalSurfaceScrollViewerStyle}"
                           VerticalScrollBarVisibility="Disabled" >
        <VirtualizingStackPanel IsItemsHost="True" Orientation="Horizontal" />
    </s:SurfaceScrollViewer>
</ControlTemplate>   

可能是因为当CanContentScroll = True时，VirtualizingStackPanel不起作用？我的内容是图片列表框。
