我需要将 Pivot 标题样式设置为这样的
我尝试使用
C# UWP Windows 10 project
I need to set Pivot header style to something like this
I has tried to use this example from stackoverflow, but not sucessful.
Can you say how I can set rectangle (like on image) behind header text and change background color for selected unselected items?
解决方案
As the answer you've mentioned, we can use PivotHeaderItem styles and templates to implement this.
Firstly, we can copy the style from MSDN and put in into Page.Resources.
Then add a Border in the Grid and set its properties like following:
<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>
This will add a border with corners like your image.
After this, we can edit the "Selected" VisualState so that when we selected the header, it can change the background and foreground:
<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>
Following is the complete XAML I used for example:
<Page x:Class="PivotUWP.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
