TabControl:

WPF TabControl-标签位置

TabControl的选项卡通常放在控件的顶部,这也是WPF TabControl默认的外观:

但是,通过使用TabStripPlacement 属性,我们能够容易的改变它:

<Window x:Class="WpfTutorialSamples.Misc_controls.TabStripPlacementSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="TabStripPlacementSample" Height="200" Width="250">
    <Grid>
        <TabControl TabStripPlacement="Bottom">
            <TabItem Header="General">
                <Label Content="Content goes here..." />
            </TabItem>
            <TabItem Header="Security" />
            <TabItem Header="Details" />
        </TabControl>
    </Grid>
</Window>

TabStripPlacement可以设置到顶部、底部、左侧和右侧。但是,如果将其设置为左侧或者右侧,则会得到如下结果:

我个人更希望当选项卡放在左右一侧时也能跟着旋转,即标签文本变为纵向显示而不是横向,但是标准功能却不是这样。不过幸运的是,我们能够通过一点小的修改达到这种效果

<Window x:Class="WpfTutorialSamples.Misc_controls.TabStripPlacementSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="TabStripPlacementSample" Height="200" Width="250" UseLayoutRounding="True">
    <Grid>
        <TabControl TabStripPlacement="Left">
            <TabControl.Resources>
                <Style TargetType="{x:Type TabItem}">
                    <Setter Property="HeaderTemplate">
                        <Setter.Value>
                            <DataTemplate>
                                <ContentPresenter Content="{TemplateBinding Content}">
                                    <ContentPresenter.LayoutTransform>
                                        <RotateTransform Angle="270" />
                                    </ContentPresenter.LayoutTransform>
                                </ContentPresenter>
                            </DataTemplate>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="Padding" Value="3" />
                </Style>
            </TabControl.Resources>
            <TabItem Header="General">
                <Label Content="Content goes here..." />
            </TabItem>
            <TabItem Header="Security" />
            <TabItem Header="Details" />
        </TabControl>
    </Grid>
</Window>

如果您尚未阅读有关模板或样式的章节,你可能会有点困惑,但我们所做的是针对TabItem元素样式的修改,我们覆盖了HeaderTemplate,然后在选项卡上运用一个旋转变换。 对于放置在左侧的标签,我们旋转270度 ;如果放置在右侧,您应该只旋转90度,使其看起来正确。
