我已经创建了一个TabControl,它将有两个选项卡项,我为这个TabControl创建了一个样式。
然而,我有一个问题,当焦点在一个TabItem,没有选择的图像显示,这个TabItem的背景将有一个蓝色。
我想删除这个蓝色的图像显示从TabItem时,做一个重点。
我已经尝试了很多方法来做到这一点,但这些方法中的任何一个对我都有效。

<TabControl Style="{StaticResource newStyle}">
        <TabItem Header="Tab 1">
            <TabItem.Style>
                <Style TargetType="TabItem">
                    <Setter Property="BorderBrush" Value="Transparent"/>
                    <Style.Triggers>
                        <Trigger Property="IsSelected" Value="true">
                            <Setter Property="BorderBrush" Value="Transparent"/>
                        </Trigger>
                        <Trigger Property="IsSelected" Value="false">
                            <Setter Property="BorderBrush" Value="Transparent"/>
                        </Trigger>
                    </Style.Triggers>
                </Style>
               
            </TabItem.Style>
            
        </TabItem>
        
        <TabItem Header="Tab 2">
            <TabItem.Style>
                <Style TargetType="TabItem">
                    <Setter Property="BorderBrush" Value="Transparent"/>
                    <Style.Triggers>
                        <Trigger Property="IsSelected" Value="true">
                            <Setter Property="BorderBrush" Value="Transparent"/>
                        </Trigger>
                        <Trigger Property="IsSelected" Value="false">
                            <Setter Property="BorderBrush" Value="Transparent"/>
                        </Trigger>
                    </Style.Triggers>
                </Style>

            </TabItem.Style>
        </TabItem>
    </TabControl>

TabItem创建自定义模板。以下是默认模板。根据您的要求修改TabItem.MouseOver.Background资源和/或触发器。

<TabControl Style="{StaticResource newStyle}">
    <TabControl.Resources>
