How to disable tab wrapping in the Tab Control object

问题

I'm designing a GUI in WPF/C# and I'm using the Tab Control object. My tab control will contain a lot of tabs, and I would like to know how to disable the default "wrapping" behavior of the object. Basically the opposite of this question. How would I go about doing that?

Thank you.

Just change the ItemsPanel:

<TabControl ....>
   <TabControl.ItemsPanel>
     <ItemsPanelTemplate>
        <StackPanel Orientation="Horizontal"/>
     </ItemsPanelTemplate>
   </TabControl.ItemsPanel>
  ....
</TabControl>

Edit:

Just tested and it doesn't work. @SimonBelanger is right.

Here is a copy of the Default Template of the TabControl, with a slight modification that changes the TabPanel to a Horizontal StackPanel:

<TabControl>
        <TabControl.Template>
            <ControlTemplate TargetType="{x:Type TabControl}">
                <Grid ClipToBounds="true" SnapsToDevicePixels="true" KeyboardNavigation.TabNavigation="Local">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition x:Name="ColumnDefinition0"/>
                        <ColumnDefinition x:Name="ColumnDefinition1" Width="0"/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition x:Name="RowDefinition0" Height="Auto"/>
                        <RowDefinition x:Name="RowDefinition1" Height="*"/>
                    </Grid.RowDefinitions>
                    <StackPanel x:Name="HeaderPanel" Grid.Column="0" IsItemsHost="true" Margin="2,2,2,0" Grid.Row="0" KeyboardNavigation.TabIndex="1" Panel.ZIndex="1" Orientation="Horizontal"/>
                    <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="Local">
                        <ContentPresenter x:Name="PART_SelectedContentHost" ContentSource="SelectedContent" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                    </Border>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="TabStripPlacement" Value="Bottom">
                        <Setter Property="Grid.Row" TargetName="HeaderPanel" Value="1"/>

                        <Setter Property="Margin" TargetName="HeaderPanel" Value="2,0,2,2"/>
                    </Trigger>
                    <Trigger Property="TabStripPlacement" Value="Left">
                        <Setter Property="Grid.Row" TargetName="HeaderPanel" Value="0"/>

                    </Trigger>
                    <Trigger Property="TabStripPlacement" Value="Right">

                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </TabControl.Template>

      ...            
    </TabControl>
