Question

我正在编写Windows 10 UWP应用程序。我创建了一个按钮，其中包含带有两个文本块的stackpanel。我想在按下时更改这些文本块的前景。

我修改了默认按钮样式。因此，单击此按钮时，BorderBrush正在更改，但文本块的前景不会更改。

<Button Command="{Binding}" Style="{StaticResource Button|SecondaryPurpleButtonStyle}" >
  <Button.Content>  
    <StackPanel Orientation="Horizontal">
      <TextBlock Margin="4" Style="{StaticResource TextBlock|MenuIconTextBlockStyle}" Foreground="{StaticResource Color|BrandLogoPurpleSolidColorBrush}"
      Text="&#xE734;" />
      <TextBlock Style="{StaticResource ThemedBodyTextBlockStyle}"  Foreground="{StaticResource Color|BrandLogoPurpleSolidColorBrush}"
      Margin="4"  Text="Add to Shortlist" />     
    </StackPanel>  
  </Button.Content>
</Button>

样式：

<Style x:Key="Button|SecondaryPurpleButtonStyle"
       TargetType="Button">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="Foreground" Value="{StaticResource Color|BrandLogoPurpleSolidColorBrush}" />

Answer 1

在您的XAML代码中，您已明确将#Set up a PSCredential: $yourPassword = ConvertTo-SecureString "<Your Password>" -AsPlainText –Force $yourCredential = New-Object -TypeName pscredential –ArgumentList "<Your UserName>", $yourPassword # Then use that credential to log in to your Azure account Login-AzureRmAccount -Credential $yourCredential -ServicePrincipal –TenantId <Your TenantId>的{{1}}属性设置为TextBlock。所以前景不会改变。

要确保文本块的前景可以更改为Foreground，请删除{StaticResource Color|BrandLogoPurpleSolidColorBrush}中的BorderBrush属性，并确保未设置Foreground属性以TextBlock的风格。

Foreground

这样TextBlock中的<Button Command="{Binding}" Style="{StaticResource Button|SecondaryPurpleButtonStyle}" > <Button.Content> <StackPanel Orientation="Horizontal"> <TextBlock Margin="4" Style="{StaticResource TextBlock|MenuIconTextBlockStyle}" Text="" /> <TextBlock Style="{StaticResource ThemedBodyTextBlockStyle}" Margin="4" Text="Add to Shortlist" /> </StackPanel> </Button.Content> </Button>将使用TextBlock的{{1}}，Button.Content可以在不同的ContentPresenter中更改。
