选中TabItem时，TabItem的背景边框与TabControl贴合着的那部分的颜色怎样一样

Question

TabItem的选中色和tabControl的背景色一样，但tabControl的边框色不一样，怎样设置tabItem与tabControl的贴合部分的边框，与tabItem的选中色，或是与tabControl的背景色一样？

tabitem和tabControl的控件模板需要设置什么吗？

Answer 1

 直接在tabcontrol上修改xaml代码即可

<TabControl  BorderThickness="0"  Padding="0"   >
 <TabItem Header="Item1"     >
                <Grid Background="Red"/>
            </TabItem>
            <TabItem Header="Item2" >
                <Grid Background="Black"/>
            </TabItem>
</TabControl>

 tabcontrol的边框是有定距离的。

 Padding为0，是将control与tabcontrol的边框距离设置为0

 BorderThickness设置为0，是将control的边框设置为0，不过太高了，可以适当修改值

你是想改变哪一部分颜色，能否给一张截图声明，选中属性为true触发：

 <Window.Resources>
        <Style TargetType="{x:Type TabItem}">
            <Style.Triggers>
                <Trigger Property="TabItem.IsSelected" Value="True">
                    <Setter Property="TabItem.FontWeight" Value="Bold"/>
                    <Setter Property="TabItem.Foreground" Value="Green"/>
                </Trigger>
               
            </Style.Triggers>
        </Style>
    </Window.Resources>

,比如这种效果，下面那个显示的“团队资源管理器”TabItem，它是选中的，它有边框，而且选中项的边框色和tabControl的是一样的，但是它贴合TabControl部分的边框颜色和tabControl的背景色是一样的，这个是怎么实现的？

Hi,

你是想设置这个Borderbrush的颜色与tabitem的背景色一样，那么你是如何设置tabitem的背景色的？

 <Grid>
        <TabControl Margin="20" BorderThickness="5" BorderBrush="Red">
            <TabItem Header="tab1"/>
            <TabItem Header="tab2"/>
            <TabItem Header="tab3"/>
        </TabControl>
    </Grid>

Best Regards,

Alex
