如何禁用Tab控件对象中的选项卡包装

Question

我正在使用WPF / C＃设计GUI，我正在使用Tab Control对象。我的tab control将包含很多标签，我想知道如何禁用对象的默认“包装”行为。基本上与this问题相反。我该怎么做呢？

谢谢。

Answer 1

只需更改ItemsPanel：

即可

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

修改

刚刚测试过，它不起作用。 @SimonBelanger是对的。

以下是TabControl的{​​{3}}的副本，稍加修改即可将TabPanel更改为水平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="Grid.Row" TargetName="ContentPanel" Value="0"/>
                        <Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
                        <Setter Property="Height" TargetName="RowDefinition1" Value="Auto"/>
                        <Setter Property="Margin" TargetName="HeaderPanel" Value="2,0,2,2"/>
                    </Trigger>
                    <Trigger Property="TabStripPlacement" Value="Left">
                        <Setter Property="Grid.Row" TargetName="HeaderPanel" Value="0"/>
                        <Setter Property="Grid.Row" TargetName="ContentPanel" Value="0"/>
                        <Setter Property="Grid.Column" TargetName="HeaderPanel" Value="0"/>

                        <Setter Property="Width" TargetName="ColumnDefinition1" Value="*"/>
                        <Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
                        <Setter Property="Height" TargetName="RowDefinition1" Value="0"/>
                        <Setter Property="Margin" TargetName="HeaderPanel" Value="2,2,0,2"/>
                    </Trigger>
                    <Trigger Property="TabStripPlacement" Value="Right">
                        <Setter Property="Grid.Row" TargetName="HeaderPanel" Value="0"/>
                        <Setter Property="Grid.Row" TargetName="ContentPanel" Value="0"/>

                        <Setter Property="Grid.Column" TargetName="ContentPanel" Value="0"/>
                        <Setter Property="Width" TargetName="ColumnDefinition0" Value="*"/>
                        <Setter Property="Width" TargetName="ColumnDefinition1" Value="Auto"/>
                        <Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
                        <Setter Property="Height" TargetName="RowDefinition1" Value="0"/>
                        <Setter Property="Margin" TargetName="HeaderPanel" Value="0,2,2,2"/>
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="false">
                        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </TabControl.Template>

      ...            
    </TabControl>
