C＃UWP Windows 10项目

我需要将Pivot标题样式设置为类似

的内容

我试图使用stackoverflow中的这个示例，但不是成功的。

您能说我如何在标题文字后面设置矩形（如图像上）并更改所选未选项目的背景颜色？

正如您提到的答案，我们可以使用PivotHeaderItem styles and templates来实现此目标。

首先，我们可以从MSDN复制样式并输入Page.Resources。

然后在Border中添加Grid并设置其属性，如下所示：

<Grid x:Name="Grid" Background="{TemplateBinding Background}">
    ...
    <Border x:Name="Border"
            BorderBrush="Gray"
            BorderThickness="2"
            CornerRadius="20">
        <ContentPresenter x:Name="ContentPresenter"
                          Margin="{TemplateBinding Padding}"
                          HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                          VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                          Content="{TemplateBinding Content}"
                          ContentTemplate="{TemplateBinding ContentTemplate}"
                          FontFamily="{TemplateBinding FontFamily}"
                          FontSize="{TemplateBinding FontSize}"
                          FontWeight="{TemplateBinding FontWeight}">
            <ContentPresenter.RenderTransform>
                <TranslateTransform x:Name="ContentPresenterTranslateTransform" />
            </ContentPresenter.RenderTransform>
        </ContentPresenter>
    </Border>
</Grid>

这将添加带有角落的边框，如图像。

在此之后，我们可以编辑“已选择”VisualState，这样当我们选择标题时，它可以更改背景和前景：

<VisualState x:Name="Selected">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="Foreground">
            <DiscreteObjectKeyFrame KeyTime="0" Value="White" />
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border" Storyboard.TargetProperty="Background">
            <DiscreteObjectKeyFrame KeyTime="0" Value="Red" />
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border" Storyboard.TargetProperty="BorderBrush">
            <DiscreteObjectKeyFrame KeyTime="0" Value="Red" />
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</VisualState>
