如何将AvalonDock Anchorable Pane选项卡移至顶部而不是底部？

Question

我在项目中使用AvalonDock并希望使用Anchorable窗格，但不是出现在底部的选项卡，而是希望它出现在顶部，就像它在文档窗格上一样。对于我的项目来说，文档窗格不是合适的控件，所以我需要找到一种方法让“可移动窗格”以同样的方式出现。

根据Issue Ticket found on CodePlex存在阻止改变TabStripPlacement顶端的一个错误。实现这一目标的方式是一个这样的替换现有的风格：

<Style x:Key="MyCustomAnchorablePaneControlStyle" TargetType="{x:Type xcad:LayoutAnchorablePaneControl}"> 

    <Setter Property="TabStripPlacement" Value="Top"/> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="{x:Type xcad:LayoutAnchorablePaneControl}"> 
       <Grid ClipToBounds="true" SnapsToDevicePixels="true" KeyboardNavigation.TabNavigation="Local"> 
        <Grid.RowDefinitions> 
         <RowDefinition Height="Auto"/> 
         <RowDefinition Height="*"/> 
        </Grid.RowDefinitions> 
        <!--Following border is required to catch mouse events--> 
        <Border Background="Transparent" Grid.RowSpan="2"/> 

        <xcad:AnchorablePaneTabPanel x:Name="HeaderPanel" Margin="2,0,2,2" IsItemsHost="true" Grid.Row="0" KeyboardNavigation.TabIndex="1" Panel.ZIndex="1"/> 

        <Border x:Name="ContentPanel" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.Column="0" KeyboardNavigation.DirectionalNavigation="Contained" Grid.Row="1" KeyboardNavigation.TabIndex="2" KeyboardNavigation.TabNavigation="Cycle"> 
         <ContentPresenter x:Name="PART_SelectedContentHost" ContentSource="SelectedContent" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> 
        </Border> 

       </Grid> 
       <ControlTemplate.Triggers> 
        <Trigger Property="IsEnabled" Value="false"> 
         <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/> 
        </Trigger> 
       </ControlTemplate.Triggers> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 

    <Setter Property="ItemContainerStyle"> 
     <Setter.Value> 
      <Style TargetType="{x:Type TabItem}"> 
       <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/> 
       <Setter Property="ToolTip" Value="{Binding ToolTip}"/> 
       <Style.Triggers> 
        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type TabControl}}, Path=Items.Count}" Value="1"> 
         <Setter Property="Visibility" Value="Collapsed"/> 
        </DataTrigger> 
       </Style.Triggers> 
      </Style> 
     </Setter.Value> 
    </Setter> 

    <Setter Property="ItemTemplate"> 
     <Setter.Value> 
      <DataTemplate> 
       <xcad:LayoutAnchorableTabItem Model="{Binding}"/> 
      </DataTemplate> 
     </Setter.Value> 
    </Setter> 

    <Setter Property="ContentTemplate"> 
     <Setter.Value> 
      <DataTemplate> 
       <xcad:LayoutAnchorableControl Model="{Binding}"/> 
      </DataTemplate> 
     </Setter.Value> 
    </Setter> 

</Style>
