更改选定的选项卡颜色WPF c＃

Question

我试图使选项卡使用相同的颜色，无论是否选中它，我都已触发并设置了颜色，但是它似乎不起作用：

<Window.Resources>
    <SolidColorBrush x:Key="TabItem.Selected.Background" Color="#424E5A"/>
    <SolidColorBrush x:Key="TabItem.Selected.Border" Color="#424E5A"/>
    <Style x:Key="TabControlStyle1" TargetType="{x:Type TabControl}">
        <Setter Property="Padding" Value="2"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Background" Value="{StaticResource TabItem.Selected.Background}"/>
        <Setter Property="BorderBrush" Value="{StaticResource TabItem.Selected.Border}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TabControl}">
                    <Grid x:Name="templateRoot" 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>

                        </Border>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="TabStripPlacement" Value="Bottom">

                            <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="Height" TargetName="RowDefinition1" Value="0"/>
                            <Setter Property="Margin" TargetName="headerPanel" Value="2,2,0,2"/>
                        </Trigger>
                        <Trigger Property="TabStripPlacement" Value="Right">

                            <Setter Property="Width" TargetName="ColumnDefinition1" Value="Auto"/>
                            <Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
                            <Setter Property="Height" TargetName="RowDefinition1" Value="0"/>

        </Setter>
    </Style>
</Window.Resources>

但是正如您所看到的，颜色是白色而不是蓝色，我的选项卡侧边栏的其余部分是：

image我该如何解决它，使颜色始终是#424E5A

我想您很亲密，只是缺少标头是在TabItem中定义的，而不是在TabControl中定义的。

因此，除了您已经拥有的样式之外，您正在寻找另一种样式。 就像是：

<Style x:Key="TabItemStyle1" TargetType="{x:Type TabItem}">
    <Setter Property="HeaderTemplate">
        <Setter.Value>
            <DataTemplate>
                <Border x:Name="grid" Background="{StaticResource TabItem.Selected.Background}">
                    <ContentPresenter>
                        <ContentPresenter.Content>
                            <TextBlock Margin="4" FontSize="15" Text="{TemplateBinding Content}"/>
                        </ContentPresenter.Content>
                    </ContentPresenter>
                </Border>
                <DataTemplate.Triggers>
                    <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type TabItem}},Path=IsSelected}" Value="True">
                        <Setter TargetName="grid" Property="Background" Value="{StaticResource TabItem.Selected.Background}"/>
                    </DataTrigger>
                </DataTemplate.Triggers>
            </DataTemplate>
        </Setter.Value>
    </Setter>

希望能帮助到你。
