水平滾動不適用於wpf列表框中的ListBox

我試圖使用此模板作爲我的列表框，但是當我使用鼠標滾輪時，水平滾動不起作用，我不知道爲什麼！水平滾動不適用於wpf列表框中的ListBox

列表框模板：

<ControlTemplate x:Key="ListBoxControlTemplate" TargetType="{x:Type ListBox}"> 
       <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="True" ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Disabled"> 
        <ScrollViewer Focusable="True" Padding="{TemplateBinding Padding}" Template="{DynamicResource ScrollViewerTargeting}" CanContentScroll="True" VerticalContentAlignment="Top" HorizontalScrollBarVisibility="Visible"> 
         <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/> 
        </ScrollViewer> 
       </Border> 
       <ControlTemplate.Triggers> 
        <Trigger Property="IsEnabled" Value="False"> 
         <Setter Property="Background" TargetName="Bd" Value="{x:Null}"/> 
         <Setter Property="BorderBrush" TargetName="Bd" Value="{x:Null}"/> 
        </Trigger> 
       </ControlTemplate.Triggers> 
      </ControlTemplate>

的ScrollViewer模板：

<ControlTemplate x:Key="ScrollViewerTargeting" TargetType="{x:Type ScrollViewer}"> 
      <Grid x:Name="Grid" Background="{TemplateBinding Background}"> 
       <Grid.ColumnDefinitions> 
        <ColumnDefinition Width="*"/> 
        <ColumnDefinition Width="Auto"/> 
       </Grid.ColumnDefinitions> 
       <Grid.RowDefinitions> 
        <RowDefinition Height="*"/> 
        <RowDefinition Height="Auto"/> 
       </Grid.RowDefinitions> 
       <Rectangle x:Name="Corner" Grid.Column="1" Fill="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" Grid.Row="1" ScrollViewer.CanContentScroll="True"/> 
       <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" CanHorizontallyScroll="True" CanVerticallyScroll="False" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Grid.Column="0" Margin="{TemplateBinding Padding}" Grid.Row="0" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/> 
       <ScrollBar x:Name="PART_VerticalScrollBar" Template="{DynamicResource ComboBoxScrollBarControlTemplate}" AutomationProperties.AutomationId="VerticalScrollBar" Cursor="Arrow" Grid.Column="1" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0" Grid.Row="0" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/> 
       <ScrollBar x:Name="PART_HorizontalScrollBar" Margin="200,0,200,20" AutomationProperties.AutomationId="HorizontalScrollBar" Cursor="Arrow" Grid.Column="0" 
        Maximum="{TemplateBinding ScrollableWidth}" Minimum="0" Grid.Row="1" 
        Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" 
        Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" 
        ViewportSize="{TemplateBinding ViewportWidth}" Template="{DynamicResource ScrollBarControlTemplate}" Focusable="True" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Disabled" Orientation="Horizontal" ScrollViewer.CanContentScroll="True"/> 
      </Grid> 
     </ControlTemplate>

滾動條的模板：

問題出在哪裏以及如何我解決呢？

你有足夠的列或橫內容使滾動發生？ –

你的例子中有太多的代碼，但它沒有包含足夠的代碼來完成。請簡化代碼示例，以便您提供了[可靠，_minimal_，_complete_代碼示例]（http://stackoverflow.com/help/mcve），可以可靠地演示此問題。 –

ScrollViewer.CanContentScroll =「True」不應該位於ItemsPresenter上，它應該通過ListBox風格進行設置。 –

的問題是在這裏：

的ScrollViewer中和邊界的位置之間

  <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="True" ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Disabled"> 
       <ScrollViewer Focusable="True" Padding="{TemplateBinding Padding}" Template="{DynamicResource ScrollViewerTargeting}" CanContentScroll="True" VerticalContentAlignment="Top" HorizontalScrollBarVisibility="Visible"> 
        <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/> 
       </ScrollViewer> 
      </Border>

嘗試切換，所以它看起來是這樣的：

  <ScrollViewer Focusable="True" Padding="{TemplateBinding Padding}" Template="{DynamicResource ScrollViewerTargeting}" CanContentScroll="True" VerticalContentAlignment="Top" HorizontalScrollBarVisibility="Visible"> 
       <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="True" ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Disabled"> 
        <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/> 
       </Border> 
      </ScrollViewer>

它不起作用。我做了一個例子，你可以看到水平滾動不起作用。 [你可以在這裏下載這個例子]（https://www.mediafire.com/?35gxn26w77zw0mh） – Shahryar

嘗試打開你的項目混合....然後右鍵單擊LBGameList在你的對象和時間軸窗口....然後選擇「分組入」並在那裏選擇滾動查看器。所以它看起來像這個http://prntscr.com/799wb2哦，不要忘記將scrollviewers水平欄設置爲自動或可見....它的默認值是禁用我想。 –
