本文介绍了如何在不设置 ContentPresenter 样式的情况下设置 TabControl 的 TabItem 样式?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个 TabControl，我对其应用了一个样式，以便 TabItems 的标题没有背景和边框.
I have a TabControl, and I apply a style to it in order for my TabItems' header to have no background nor border.
我的问题是，如果我为选定的触发器添加触发器，相应的面板也会设置样式.因此，如果我选择将所选 TabItem 的前景设置为红色，面板的文本块也会变为红色.
My problem is that if I add a trigger for the selected one, the corresponding panel get styled as well. So if I choose to set the selected TabItem's foreground to Red, the panel's textblocks become red as well.
有趣的事实:它不适用于标签.我很迷茫.
Fun fact: it doesn't apply to Labels. I'm quite lost.
这是 XAML，它在 Kaxaml 中的测试速度非常快:
Here's the XAML, that tests pretty fast in Kaxaml:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<TabControl>
<TabControl.Resources>
<Style TargetType="{x:Type TabItem}">
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect ShadowDepth="0" Color="Black" BlurRadius="3"/>
</Setter.Value>
</Setter>
<Setter Property="RenderTransformOrigin" Value="0.5,0.5"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="12,2,12,2" RecognizesAccessKey="True"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Foreground" Value="DarkOrange"/>
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect ShadowDepth="0" BlurRadius="4" Color="Blue"/>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="#FF553333" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
<TabItem Header="TAB1">
<TextBlock Text="WHY AM I GETTING STYLED D:"/>
</TabItem>
<TabItem Header="TAB2">
<TextBlock Text="ME TOO D:"/>
</TabItem>
</TabControl>
</Grid>
</Window>
