Pivot Header风格

Question

C#UWP Windows 10项目

我需要将Pivot标题样式设置为这样的东西

我试图从stackoverflow使用这个例子,但不是成功的.

你能说我如何在标题文本后面设置矩形(如图像)并更改所选未选项的背景颜色？

作为您提到的答案,我们可以使用PivotHeaderItem样式和模板来实现这一点.

首先,我们可以从MSDN复制样式并输入Page.Resources.

然后添加一个Border在Grid并设置其属性,如下列:

<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,就像您的图像一样.

在此之后,我们可以编辑"Selected",VisualState这样当我们选择标题时,它可以改变背景和前景:

<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>

以下是我用过的完整XAML:
