WPF的GridView头不水平滚动

我有一个的ScrollViewer其用于与在GridView的内容沿水平滚动一个GridView。我使用Chris Cavanagh's rounded corners solution，其包括将周围的GridViewHeaderRowPresenter网格和添加边框至相同的水平，然后将其用作不透明掩模（see this question for more information）改变它。WPF的GridView头不水平滚动

这似乎禁用水平滚动的标题。如果我将浏览器窗口的大小调整为小一点，强制滚动条显示内容，则标题保持不变。我想象添加的xaml以某种方式禁用了标题的滚动。

这就是代码当前的模样。请注意，这是在一个定义ScrollViewer元素的样式定义中，而不是直接在页面上的XAML标记中。

<ScrollViewer Focusable="false" 
       HorizontalScrollBarVisibility="Hidden" 
       VerticalScrollBarVisibility="Hidden" 
       DockPanel.Dock="Top" 
       Style="{DynamicResource HEK_ScrollViewer}"> 
    <Grid> 
     <Border Name="Mask" 
       CornerRadius="20,20,0,0" 
       Background="White" /> 
     <GridViewHeaderRowPresenter Margin="1,0,1,1" 
            SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" 
            Columns="{Binding TemplatedParent.View.Columns, RelativeSource={RelativeSource TemplatedParent}}" 
            AllowsColumnReorder="{Binding TemplatedParent.View.AllowsColumnReorder, RelativeSource={RelativeSource TemplatedParent}}" 
            ColumnHeaderContainerStyle="{DynamicResource HEK-GridViewColumnHeaderStyle}" 
            ColumnHeaderContextMenu="{Binding TemplatedParent.View.ColumnHeaderContextMenu, RelativeSource={RelativeSource TemplatedParent}}" 
            ColumnHeaderStringFormat="{Binding TemplatedParent.View.ColumnHeaderStringFormat, RelativeSource={RelativeSource TemplatedParent}}" 
            ColumnHeaderTemplate="{Binding TemplatedParent.View.ColumnHeaderTemplate, RelativeSource={RelativeSource TemplatedParent}}" 
            ColumnHeaderTemplateSelector="{Binding TemplatedParent.View.ColumnHeaderTemplateSelector, RelativeSource={RelativeSource TemplatedParent}}" 
            ColumnHeaderToolTip="{Binding TemplatedParent.View.ColumnHeaderToolTip, RelativeSource={RelativeSource TemplatedParent}}"> 
      <GridViewHeaderRowPresenter.OpacityMask> 
       <VisualBrush Visual="{Binding ElementName=Mask}" /> 
      </GridViewHeaderRowPresenter.OpacityMask> 
     </GridViewHeaderRowPresenter> 
    </Grid> 
</ScrollViewer>

我不确定是什么导致了这种行为。我猜在ListView中有一些代码需要一个GridViewHeaderRowPresenter作为头ScrollViewer的直接子元素。

但是，如果你动起来的网格，父母给的ScrollViewer，它正确地滚动。

<DockPanel Margin="{TemplateBinding Padding}"> 
    <Grid DockPanel.Dock="Top"> 
     <Border Name="Mask" CornerRadius="4,4,0,0" Background="White" /> 
     <ScrollViewer 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}}" ColumnHeaderContextMenu="{Binding TemplatedParent.View.ColumnHeaderContextMenu, RelativeSource={RelativeSource TemplatedParent}}" ColumnHeaderTemplate="{Binding TemplatedParent.View.ColumnHeaderTemplate, RelativeSource={RelativeSource TemplatedParent}}" Columns="{Binding TemplatedParent.View.Columns, RelativeSource={RelativeSource TemplatedParent}}" Margin="2,0" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"> 
       <GridViewHeaderRowPresenter.OpacityMask> 
        <VisualBrush Visual="{Binding ElementName=Mask}" /> 
       </GridViewHeaderRowPresenter.OpacityMask> 
      </GridViewHeaderRowPresenter> 
     </ScrollViewer> 
    </Grid> 
    <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" CanHorizontallyScroll="False" CanVerticallyScroll="False" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" KeyboardNavigation.DirectionalNavigation="Local" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> 
</DockPanel>

虽然是旧帖子，但是如果有人有同样的问题。这有点类似于上面的Tedy Pranolo的解决方案。我有这个问题，网格标题不会随内容一起滚动。添加只是一个GridViewHeaderRowPresenter的ScrollViewer在ControlTemplate中的ScrollViewer中（对于ListView控件）解决了这个问题对我来说。这是一个有固定的问题XAML的一部分：

<DockPanel Margin="{TemplateBinding Padding}"> 
         <ScrollViewer DockPanel.Dock="Top" VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="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>

这是当问题是存在的XAML：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
       xmlns:interactivity="clr-namespace:XYZ.WPF.Interactivity;assembly=XYZ.WPF"> 
<Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}" TargetType="{x:Type ScrollViewer}"> 
    <Setter Property="interactivity:MouseWheelBubbleBehavior.BehaviorSource" Value="{Binding RelativeSource={RelativeSource Self}}"/> 
    <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}"> 
         <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}"/> 
         <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>

通知失踪的ScrollViewer封闭GridViewHeaderRowPresenter。

希望这有助于！
