摆脱标签控件的该选项卡下的行

使用xaml（wpf）我试图摆脱下面的“插图A”中显示的选项卡控件下的行，以便它最终看起来像“插图B”：摆脱标签控件的该选项卡下的行

钍当我定义选项卡项目但显示为附加到选项卡控件时，e行显示出来，因为在选项卡项目或选项卡控件中的任一个或两个上更改BorderThickness似乎不会产生所需的结果。

我需要通过透明背景来做到这一点，其中实心填充矩形不能用来掩盖问题。

下面的代码：

<!--Tab Control--> 
<Style TargetType="{x:Type TabControl}"> 
    <Setter Property="OverridesDefaultStyle" Value="True" /> 
    <Setter Property="SnapsToDevicePixels" Value="True" />

我可能会丢失一些东西，但tabitem的默认tabcontrol不会在您的插图中有该行。你在谈论未被选中的标签吗？见http://blog.paranoidferret.com/index.php/2008/01/18/the-wpf-tab-control-inside-and-out/那里的图片没有显示该行。 – Jab 2008-12-30 15:15:27

我也曾见过。如果仔细观察，前几个插图在选定选项卡下面没有行，但最后几个（在定义tabitem之后）在它们下面有一行。 – Rob 2008-12-30 15:24:24

使用ShowMeTheTemplate我发现了风格的一部分，它是在TabItem的。如果您覆盖它，您可能有兴趣设置的默认控制模板中还有很多。

<MultiTrigger> 
    <MultiTrigger.Conditions> 
    <Condition Property="Selector.IsSelected"> 
     <Condition.Value> 
     <s:Boolean>True</s:Boolean> 
     </Condition.Value> 
    </Condition> 
    <Condition Property="TabItem.TabStripPlacement" Value="{x:Static Dock.Top}" /> 
    </MultiTrigger.Conditions> 
    <Setter Property="FrameworkElement.Margin"> 
    <Setter.Value> 
     <Thickness>-2,-2,-2,-1</Thickness> 
    </Setter.Value> 
    </Setter> 
</MultiTrigger>

这工作得很好。

<Style TargetType="TabItem"> 
    <Setter Property="VerticalContentAlignment" Value="Stretch"/> 
    <Setter Property="HorizontalContentAlignment" Value="Stretch"/> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="{x:Type TabItem}"> 
       <Border x:Name="Chrome" 
         BorderThickness="1,1,1,0" 
         BorderBrush="Black" 
         Background="{TemplateBinding Background}" 
         Padding="2,2,2,1" Margin="1,1,1,0"> 
        <ContentPresenter ContentSource="Header" 
         HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
         VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> 
       </Border> 
       <ControlTemplate.Triggers> 
        <Trigger Property="Selector.IsSelected" Value="True"> 
         <Setter TargetName="Chrome" Property="Margin" Value="1,1,1,-1"/> 
         <Setter TargetName="Chrome" Property="Padding" Value="2"/> 
        </Trigger> 
       </ControlTemplate.Triggers> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style>

只需更改所选标签项目上的边距和填充。

调整边距和填充不适合我。画一个白色（背景颜色）边境上的标签控制边界的伎俩但是：

<ControlTemplate TargetType="{x:Type TabItem}"> 
<StackPanel VerticalAlignment="Center" HorizontalAlignment="Center" Margin="0 0 7 0"> 
     <Border x:Name="tabContentBorder" BorderThickness="2 2 2 0" Background="AliceBlue" BorderBrush="AliceBlue" CornerRadius="6 6 0 0"> 
     <ContentPresenter HorizontalAlignment="Center" x:Name="Content" VerticalAlignment="Center" ContentSource="Header" Margin="7 3 7 3"/> 
    </Border> 
    <Border x:Name="tabBottomBorder" BorderBrush="White" BorderThickness="1" Visibility="Hidden" Margin="2 0 2 -2" HorizontalAlignment="Stretch"></Border> 
</StackPanel> 
<ControlTemplate.Triggers> 
    <Trigger Property="IsSelected" Value="True"> 
     <Setter TargetName="tabContentBorder" Property="Background" Value="White" /> 
     <Setter TargetName="tabBottomBorder" Property="Visibility" Value="Visible"/> 
    </Trigger> 
</ControlTemplate.Triggers>

有同样的问题。注意到该行仅为设置了高度的选项卡绘制（它仅设置为一个选项卡，并自动将所有选项卡设置为存储高度）。所以我添加了一个新的TabItem与width=0和height指定并从所有其他选项卡中删除height并为我制造了诀窍。

另一种非常简单的方法是只需添加一个额外的标签宽度为零，你可以设置高度为你想要的东西，甚至只是做它的可见性隐藏。然后，您可以设置选项卡高度，而不需要在设置高度的选项卡上使用恼人的水平线。

  <TabItem Header="" Width="0" Height="30" Visibility="Hidden" />
