XAML 无头透视
XAML Pivot Headerless
我正在寻找更改我的数据透视表样式以在 header 中不留空 space。
这是我页面的图片：
蓝色部分是来自模板 10 的控件 header。
白色部分是空 space 距枢轴 header 的高度。
绿色部分是命令条（在枢轴内部）。
我不能在数据透视表中使用负边距，因为我的页面header 包含一个二级菜单，而这个结果被屏蔽了。
我写了一个样式来设置枢轴的高度header，但效果不佳。
<Page.Resources>
<Style x:Key="PivotHeaderless" TargetType="PivotItem">
<Setter Property="Margin" Value="0"/>
<Setter Property="Header" Value=""/>
<Setter Property="Height" Value="0"/>
</Style>
</Page.Resources>
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<StackPanel>
<Pivot x:Name="MainPivot">
<PivotItem Style="{ThemeResource PivotHeaderless}"/>
</Pivot>
</StackPanel>
</Grid>
感谢任何帮助。
为此，您必须更改控件本身的模板。
如果您导航到 C:\Program Files (x86)\Windows Kits\DesignTime\CommonConfiguration\Neutral\UAP\<SDKVERSION>\Generic\generic.xaml，您会发现 Pivot 控件的默认模板包含以下内容：
<PivotPanel x:Name="Panel" VerticalAlignment="Stretch">
<Grid x:Name="PivotLayoutElement">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<!-- ... more code -->
</Grid>
网格第一行的高度为Auto。这意味着它的高度被设置为适应所包含的内容。但是这个 header 不仅包含你的枢轴项的 header，还有两个用于分页的控制按钮 - Previ:
<Button x:Name="PreviousButton"
Grid.Column="1"
Template="{StaticResource PreviousTemplate}"
Width="20"
Height="36"
... />
<Button x:Name="NextButton"
Grid.Column="1"
Template="{StaticResource PreviousTemplate}"
Width="20"
Height="36"
... />
如您所见，这些按钮的高度被硬编码为 36 像素，这意味着无论您做什么，如果您不对它们做任何事情，header 将始终处于至少 36 像素的高度。
解决方案
最简单的解决方案是创建 Pivot 控件默认模板的副本（例如通过从 generic.xaml 文件复制 Style 定义）并设置第一个Grid的行高为0。这将有效地隐藏它并使其不可见。为了使它更有效，您可以删除第一行中的所有控件，这样它们就不会被构建，从而提高性能：
<PivotPanel x:Name="Panel" VerticalAlignment="Stretch">
<Grid x:Name="PivotLayoutElement">
<Grid.RowDefinitions>
<RowDefinition Height="0" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Grid.RenderTransform>
<CompositeTransform x:Name="PivotLayoutElementTranslateTransform" />
</Grid.RenderTransform>
<ItemsPresenter x:Name="PivotItemPresenter" Grid.Row="1" Grid.ColumnSpan="3">
<ItemsPresenter.RenderTransform>
<TransformGroup>
<TranslateTransform x:Name="ItemsPresenterTranslateTransform" />
<CompositeTransform x:Name="ItemsPresenterCompositeTransform" />
</TransformGroup>
</ItemsPresenter.RenderTransform>
</ItemsPresenter>
</Grid>
</PivotPanel>
