Windows 8应用程序,更改BackButtonStyle的颜色

我正在创建一个默认情况下请求黑暗主题的Windows商店应用程序。 除了其中一页需要白色以外,这很好。 我把所有内容放在一个网格中,并将背景更改为白色..一切工作正常,除了我的导航按钮的样式为:

<Button Foreground="Black" x:Name="backButton" Click="GoBack" IsEnabled="{Binding Frame.CanGoBack, ElementName=pageRoot}" Style="{StaticResource BackButtonStyle}" />

{StaticResource BackButtonStyle}返回一个白色按钮(由于我的Apps Dark主题),所以后退按钮在白色背景下不可见。

如何将此后退按钮的颜色更改为黑色? 即它会在黑色圆圈内显示一个黑色箭头。

我试过在StandardStyles.xaml中创建自己的风格,没有任何喜悦:

<Style x:Key="PortraitBackButtonStyle" TargetType="Button" BasedOn="{StaticResource BackButtonStyle}">
    <Setter Property="Margin" Value="26,0,26,36"/>
</Style>

谢谢!


将此样式放入StandardStyles.xaml文件中,并将其用于后退按钮中

如果您的背景为白色您可以在后退按钮属性中编写以下代码:

   <Button x:Name="backButton" Margin="39,59,39,0" Command="{Binding NavigationHelper.GoBackCommand, ElementName=pageRoot}"
  Style="{StaticResource NavigationBackButtonNormalStyle}"
                            VerticalAlignment="Top"
                            AutomationProperties.Name="Back"
                            RequestedTheme="Light"
                            AutomationProperties.AutomationId="BackButton"
                            AutomationProperties.ItemType="Navigation Button"/>

有一个明显的解决方案 - 重新设计控件。 但是,每次需要将控件添加到UI时,您都不想输入样式名称。 另外,您通常在深色背景上使用输入控件,因此您甚至不需要两种不同的样式。 在这种情况下,可以使用不同的方法。

解决方案:

首先,打开:

C: Program Files(x86) Windows Kits 8.0 Include winrt xaml design themeresources.xaml

并搜索“Dark”ResourceDictionary声明。 复制与buttonsa关联的所有SolidColorBrush对象定义,并最终将所有画笔粘贴到资源字典中,然后使用它。
