C# 如何在 Windows Phone 8 中更改枢轴标题模板

How to Change Pivot Header Template in Windows Phone 8

提问by Matthew

I would like to be able to change the background of the Pivot Headers and Application Title in Windows Phone 8. From what I gather, I must create a custom style targeting the Pivot control. I am not sure, however, to change the background of only the headers?

我希望能够在 Windows Phone 8 中更改 Pivot 标题和应用程序标题的背景。根据我收集的信息，我必须创建一个针对 Pivot 控件的自定义样式。但是，我不确定是否只更改标题的背景？

I would like to adjust the style somehow

我想以某种方式调整样式

<Style x:Key="MyPivotStyle" TargetType="phone:Pivot">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="phone:Pivot">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>
                <Grid CacheMode="BitmapCache" Grid.RowSpan="2">
                    <Grid.Background>
                        <ImageBrush ImageSource="/Assets/bg_header.png"/>
                    </Grid.Background>
                </Grid>
                <Grid Background="{TemplateBinding Background}" CacheMode="BitmapCache" Grid.Row="2" />
                <ContentPresenter ContentTemplate="{TemplateBinding TitleTemplate}" Margin="24,17,0,-7">
                    <StackPanel Orientation="Horizontal">

            </Grid>
        </ControlTemplate>
    </Setter.Value>
</Setter>

EDITED for WinRT (sorry for the delay and thanks for the reminder to update this answer): To edit a full template right click on the control when in Document Outline and select Edit Template - Current (in Visual Studio or Blend) and the template will be generated for you and you can edit as you want, see my answer here for screenshots.

为 WinRT 编辑（抱歉延迟并感谢提醒更新此答案）：要编辑完整模板，请在文档大纲中右键单击控件，然后选择编辑模板 - 当前（在 Visual Studio 或 Blend 中），模板将为您生成，您可以根据需要进行编辑，请在此处查看我的答案以获取屏幕截图。

Here are the two examples below (posted in 2013) redone for Windows Phone Windows Runtime:

以下是为 Windows Phone Windows Runtime 重做的以下两个示例（于 2013 年发布）：

<Grid Background="Transparent">
    <Pivot Title="Re-templating example">
        <Pivot.HeaderTemplate>
            <DataTemplate>
                <Grid Background="Blue">
                    <TextBlock Text="{Binding}" />
                </Grid>
            </DataTemplate>
        </Pivot.HeaderTemplate>
        <Pivot.TitleTemplate>
            <DataTemplate>
                <Grid Background="Green">
                    <TextBlock Text="{Binding}" />
                </Grid>
            </DataTemplate>
        </Pivot.TitleTemplate>
        <PivotItem Header="One">
            <TextBlock FontSize="35"
                        Text="This is item one" />
        </PivotItem>
        <PivotItem Header="Two">
            <TextBlock FontSize="35"
                        Text="This is item 2" />
        </PivotItem>
    </Pivot>
</Grid>

And second example, notice that we are wrapping the ContentPresenter in a Grid (you could use a border as well or any other element):

第二个示例，请注意我们将 ContentPresenter 包装在 Grid 中（您也可以使用边框或任何其他元素）：

<Page.Resources>
    <SolidColorBrush x:Key="PivotBackground" Color="#FFE46C08"/>

    <Style x:Key="PivotStyle" TargetType="Pivot">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Pivot">
                    <Grid x:Name="RootElement" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <!--Notice that ContentControl is wrapped in a Grid and Background set to resource furtehr up-->
                        <Grid VerticalAlignment="Center" Background="{StaticResource PivotBackground}">
                            <ContentControl x:Name="TitleContentControl" ContentTemplate="{TemplateBinding TitleTemplate}" Content="{TemplateBinding Title}" Style="{StaticResource PivotTitleContentControlStyle}"/>
                        </Grid>
                        <ScrollViewer x:Name="ScrollViewer" HorizontalSnapPointsAlignment="Center" HorizontalSnapPointsType="MandatorySingle" HorizontalScrollBarVisibility="Hidden" Margin="{TemplateBinding Padding}" Grid.Row="1" Template="{StaticResource ScrollViewerScrollBarlessTemplate}" VerticalSnapPointsType="None" VerticalScrollBarVisibility="Disabled" VerticalScrollMode="Disabled" VerticalContentAlignment="Stretch" ZoomMode="Disabled">
                            <PivotPanel x:Name="Panel" VerticalAlignment="Stretch">
                                <!--Background set to resource further up-->
                                <PivotHeaderPanel Background="{StaticResource PivotBackground}" x:Name="Header" >
                                    <PivotHeaderPanel.RenderTransform>
                                        <CompositeTransform x:Name="HeaderTranslateTransform" TranslateX="0"/>
                                    </PivotHeaderPanel.RenderTransform>
                                </PivotHeaderPanel>
                                <ItemsPresenter x:Name="PivotItemPresenter">
                                    <ItemsPresenter.RenderTransform>
                                        <TranslateTransform x:Name="ItemsPresenterTranslateTransform" X="0"/>
                                    </ItemsPresenter.RenderTransform>
                                </ItemsPresenter>
                            </PivotPanel>
                        </ScrollViewer>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Page.Resources>

Using the above style:

使用上述样式：

<Grid Background="Transparent">
    <Pivot Style="{StaticResource PivotStyle}"
            Title="Re-templating example">
        <PivotItem Header="One">
            <TextBlock FontSize="35" Text="This is item one" />
        </PivotItem>
        <PivotItem Header="Two">
            <TextBlock FontSize="35" Text="This is item 2"/>
        </PivotItem>
    </Pivot>
</Grid>

By the way, it's usually preferred to keep styles in a separate style file- I've only kept them on the same page for simplicity for this example. If you remove the x:key attribute the style will be applied to all the controls of the set target type (Pivot in this example).

顺便说一句，通常更喜欢将样式保存在单独的样式文件中 - 为了本示例的简单起见，我仅将它们保存在同一页面上。如果删除 x:key 属性，则样式将应用于设置的目标类型（本例中为 Pivot）的所有控件。

Answer from 2013 for Windows Phone 7.X and Windows Phone 8 (WP Silverlight:

2013 年针对 Windows Phone 7.X 和 Windows Phone 8 的回答（WP Silverlight：

There are a few ways you can do it, but here is one example:

有几种方法可以做到这一点，但这里有一个例子：

<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>  
    </Grid.RowDefinitions>

    <phone:Pivot Grid.Row="1">
        <phone:Pivot.HeaderTemplate>
            <DataTemplate>
                <Grid Background="Red" Height="200">
                    <TextBlock Text="{Binding}"/>
                </Grid>
            </DataTemplate>
        </phone:Pivot.HeaderTemplate>
        <phone:PivotItem Header="Test">
            <TextBlock Text="ghjgb"/>
        </phone:PivotItem>
        <phone:PivotItem Header="Test">
            <TextBlock Text="ghjgb"/>
        </phone:PivotItem>
    </phone:Pivot>

If you however want to do this:

但是，如果您想这样做：

You can do this, remove the x:key to apply to all pivoits, or use the key to set the style on just selected pivoit elements like so:

您可以执行此操作，删除 x:key 以应用于所有枢轴，或使用该键在仅选定的枢轴元素上设置样式，如下所示：

<controls:Pivot Title="The Marathon Runner" Style="{StaticResource PivotStyle}">
    <Style x:Key="PivotStyle" TargetType="phone:Pivot">
        <Setter Property="Margin" Value="0"/>
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="ItemsPanel">
            <Setter.Value>
                <ItemsPanelTemplate>
                    <Grid/>
                </ItemsPanelTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="phone:Pivot">
                    <Grid HorizontalAlignment="{TemplateBinding HorizontalAlignment}"
      VerticalAlignment="{TemplateBinding VerticalAlignment}">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <Grid Background="#ff9000" CacheMode="BitmapCache" Grid.RowSpan="2" />
                        <Grid Background="{TemplateBinding Background}" CacheMode="BitmapCache"
        Grid.Row="2" />
                        <ContentPresenter ContentTemplate="{TemplateBinding TitleTemplate}"
                    Content="{TemplateBinding Title}" Margin="24,17,0,-7"/>
                        <Primitives:PivotHeadersControl x:Name="HeadersListElement"
                                          Grid.Row="1"/>
                        <ItemsPresenter x:Name="PivotItemPresenter"
                  Margin="{TemplateBinding Padding}" Grid.Row="2"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
