【问题描述】：
有没有办法自定义常用的 WPF ListView 控件，以便它在显示其 GridView 时使用 SurfaceScrollViewer（来自 Microsoft Surface Toolkit for Windows Touch Beta）而不是常用的 ScrollViewer？
我已尝试查看 XAML files that describe the stock ListView control，但我是 WPF 编程新手，因此我不确定如何针对我想要的行为自定义 XAML。
我尝试使用 Expression Blend 来重新模板库存列表框控件以使用 SurfaceScrollViewer，并最终得到了这个模板：
<Style x:Key="SurfaceListView" TargetType="{x:Type ListView}">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
<Setter Property="BorderBrush" Value="{StaticResource ListBorder}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="#FF042271"/>
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
<Setter Property="ScrollViewer.CanContentScroll" Value="true"/>
<Setter Property="ScrollViewer.PanningMode" Value="Both"/>
<Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListView}">
<Microsoft_Windows_Themes:ListBoxChrome x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderFocused="{TemplateBinding IsKeyboardFocusWithin}" SnapsToDevicePixels="true">
<s:SurfaceScrollViewer Padding="{TemplateBinding Padding}" Style="{DynamicResource {x:Static GridView.GridViewScrollViewerStyleKey}}">
<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</s:SurfaceScrollViewer>
</Microsoft_Windows_Themes:ListBoxChrome>
<ControlTemplate.Triggers>
<Trigger Property="IsGrouping" Value="true">
<Setter Property="ScrollViewer.CanContentScroll" Value="false"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
然而，这并没有产生我想要的效果，因为 GridView 似乎劫持了滚动行为，而且它仍然是逐行的，而不是我对 SurfaceScrollViewer 所期望的平滑平移。我怀疑问题可能出在以下 ScrollViewer 模板上，该模板也在模板中定义：
<Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}" TargetType="{x:Type ScrollViewer}">
<Setter Property="Focusable" Value="false"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollViewer}">
<Grid Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<DockPanel Margin="{TemplateBinding Padding}">
<ScrollViewer DockPanel.Dock="Top" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden">
<GridViewHeaderRowPresenter AllowsColumnReorder="{Binding TemplatedParent.View.AllowsColumnReorder, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderContainerStyle="{Binding TemplatedParent.View.ColumnHeaderContainerStyle, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderToolTip="{Binding TemplatedParent.View.ColumnHeaderToolTip, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderStringFormat="{Binding TemplatedParent.View.ColumnHeaderStringFormat, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderContextMenu="{Binding TemplatedParent.View.ColumnHeaderContextMenu, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderTemplate="{Binding TemplatedParent.View.ColumnHeaderTemplate, RelativeSource={RelativeSource TemplatedParent}}" Columns="{Binding TemplatedParent.View.Columns, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderTemplateSelector="{Binding TemplatedParent.View.ColumnHeaderTemplateSelector, RelativeSource={RelativeSource TemplatedParent}}" Margin="2,0,2,0" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</ScrollViewer>
<ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" KeyboardNavigation.DirectionalNavigation="Local" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</DockPanel>
<ScrollBar x:Name="PART_HorizontalScrollBar" Cursor="Arrow" Maximum="{TemplateBinding ScrollableWidth}" Minimum="0.0" Orientation="Horizontal" Grid.Row="1" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportWidth}"/>
<ScrollBar x:Name="PART_VerticalScrollBar" Cursor="Arrow" Grid.Column="1" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0.0" Orientation="Vertical" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}"/>
<DockPanel Background="{Binding Background, ElementName=PART_VerticalScrollBar}" Grid.Column="1" LastChildFill="false" Grid.Row="1">
<Rectangle DockPanel.Dock="Left" Fill="White" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Width="1"/>
<Rectangle DockPanel.Dock="Top" Fill="White" Height="1" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"/>
</DockPanel>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我不确定如何重新模板化，因为简单地将 ScrollViewer 的所有实例替换为 s:SurfaceScrollViewer 似乎没有任何效果。
我的后备计划是只使用 SurfaceListBox 控件而不是 ListView，但如果可能的话，我已经有我希望修改的工作 ListView/GridView 代码（以获得 SurfaceScrollViewer 提供的良好触摸平移）。
更新：
在尝试了 ListView/GridView 组合之后，我最终放弃了，并将其实现为一个数据绑定的 SurfaceListBox，其中包括一个水平 StackPanel 作为 SurfaceListBoxItem。到目前为止，它似乎运作良好。
