WPF的GridView頭不水平滾動

我有一個的ScrollViewer其用於與在GridView的內容沿水平滾動一個GridView。我使用Chris Cavanagh's rounded corners solution，其包括將周圍的GridViewHeaderRowPresenter網格和添加邊框至相同的水平，然後將其用作不透明掩模（see this question for more information）改變它。WPF的GridView頭不水平滾動

這似乎禁用水平滾動的標題。如果我將瀏覽器窗口的大小調整爲小一點，強制滾動條顯示內容，則標題保持不變。我想象添加的xaml以某種方式禁用了標題的滾動。

這就是代碼當前的模樣。請注意，這是在一個定義ScrollViewer元素的樣式定義中，而不是直接在頁面上的XAML標記中。

<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>

我不確定是什麼導致了這種行爲。我猜在ListView中有一些代碼需要一個GridViewHeaderRowPresenter作爲頭ScrollViewer的直接子元素。

但是，如果你動起來的網格，父母給的ScrollViewer，它正確地滾動。

<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>

雖然是舊帖子，但是如果有人有同樣的問題。這有點類似於上面的Tedy Pranolo的解決方案。我有這個問題，網格標題不會隨內容一起滾動。添加只是一個GridViewHeaderRowPresenter的ScrollViewer在ControlTemplate中的ScrollViewer中（對於ListView控件）解決了這個問題對我來說。這是一個有固定的問題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>

這是當問題是存在的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>

通知失蹤的ScrollViewer封閉GridViewHeaderRowPresenter。

希望這有助於！
