TabItem 标题垂直

Question

所以我得到了一个带有一些 Tabitems 和几个按钮的 TabControl。

当我按下这些按钮时，会改变 TabStrip 的位置。

一切正常。 我现在想做的是，

当我按下按钮 Right90 将标签条向右放置时，标题应旋转 90°。

我尝试过，但总是失败。

我会很高兴得到一个快速的答复。

这是我的代码：

您需要编写两种不同的样式并在按钮单击时设置它们

在您的窗口资源中

<Window.Resources>
<Style x:Key="Right90" TargetType="{x:Type TabItem}">           
        <Setter Property="HeaderTemplate">
            <Setter.Value>
                <DataTemplate>
                    <ContentPresenter Content="{TemplateBinding Content}" TextOptions.TextFormattingMode="Display">
                        <ContentPresenter.LayoutTransform>
                            <RotateTransform Angle="90" />
                        </ContentPresenter.LayoutTransform>
                    </ContentPresenter>
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <Style x:Key="Left90" TargetType="{x:Type TabItem}">          
        <Setter Property="HeaderTemplate">
            <Setter.Value>
                <DataTemplate>
                    <ContentPresenter Content="{TemplateBinding Content}" TextOptions.TextFormattingMode="Display">
                        <ContentPresenter.LayoutTransform>
                            <RotateTransform Angle="-90" />
                        </ContentPresenter.LayoutTransform>
                    </ContentPresenter>
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>

</Window.Resources>

这是您的 TabControl 和按钮

<DockPanel>
    <Button Name="btnRight" DockPanel.Dock="Top" Click="btnRight_Click" Content="Right"></Button>
    <Button Name="btnLeft" DockPanel.Dock="Top" Click="btnLeft_Click" Content="Left" ></Button>
    <TabControl Name="tabControl">
        <TabItem Header="Tab1"></TabItem>
        <TabItem Header="Tab2"></TabItem>
    </TabControl>
</DockPanel>

这就是后面的代码的运行方式

    private void btnLeft_Click(object sender, RoutedEventArgs e)
    {
        tabControl.TabStripPlacement = Dock.Left;
        tabControl.ItemContainerStyle = this.FindResource("Left90") as Style;
    }

    private void btnRight_Click(object sender, RoutedEventArgs e)
    {
        tabControl.TabStripPlacement = Dock.Right;
        tabControl.ItemContainerStyle = this.FindResource("Right90") as Style;
    }

Answer 2

在项目模板的触发器中，添加这个触发器：

<Trigger Property="TabStripPlacement" Value="Right">
    <Setter TargetName="Content" Property="LayoutTransform">
        <Setter.Value>
            <RotateTransform Angle="90"/>
        </Setter.Value>
    </Setter>
</Trigger>
