如何设置PivotItem标题的样式

Posted 2021-05-04

我有一个正在使用的现有Pivot标头模板，但是并不能满足我的需要。我需要当前选择的PivotItem具有蓝色前景和白色背景，而所有其他枢轴项目都具有标准的禁用前景和背景外观。目前在下面，我相信除了选定的PivotItem上的蓝色前景外，其他所有东西都可以，但是我无法弄清楚如何仅将前景正确地应用于所选项目？

答案

将<ContentPresenter>更改为<TextBlock>

像这样

<Style x:Key="PivotHeaderItemStyle1" TargetType="Primitives:PivotHeaderItem">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="Padding" Value="10,0,10,0"/>
    <Setter Property="Margin" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Primitives:PivotHeaderItem">
                <Grid>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="SelectionStates">
                            <VisualState x:Name="Unselected">
                                <Storyboard>
                                    <ColorAnimation Duration="0" Storyboard.TargetName="border_highlight" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="Transparent"/>
                                    <ColorAnimation  Duration="0" Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" To="Green"/>
                                </Storyboard>
                            </VisualState>
                            <VisualState x:Name="Selected">
                                <Storyboard>
                                    <ColorAnimation  Duration="0:0:1" Storyboard.TargetName="border_highlight" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="PaleGreen"/>
                                    <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="contentPresenter"/>
                                    <ColorAnimation  Duration="0" Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" To="Blue"/>
                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                    <Border x:Name="border_highlight" Background="{TemplateBinding Background}" >
                        <!--<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"/>-->
                        <TextBlock x:Name="contentPresenter" Foreground="{TemplateBinding Foreground}" Text="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"></TextBlock>
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后您可以为前景制作动画。这是上述代码的屏幕截图。选择颜色=蓝色，未选择颜色=绿色。不过，您将需要重新添加背景动画。

@@ Teysz，我认为您最好使用Windows 10 UWP从PivotItemHeader的默认样式开始，并在XAML文件的..Resources部分中进行复制。 Visual Studio 2015无法插入默认样式，因此您必须从以下位置获取它：%ProgramFiles(x86)%Windows Kits10DesignTimeCommonConfigurationNeutralUAP10.0.10240.0Genericgeneric.xaml我在http://blog.hompus.nl/2015/09/04/responsive-pivot-headers-in-universal-windows-platform-apps/找到了这个>
