Windows手机样式更新不工作

Question

我在我的windows phone 7.1应用程序中应用了样式到文本块，这反映在VS设计器中。但是当我运行它时，根本看不到任何更改。代码运行没有错误，除了在调试时更改丢失，并且背景属性在设计器和调试模式下没有显示任何更改。

在您的Application.Resources标签中尝试此代码

<Application.Resources>
    <Style TargetType="TextBlock" x:Key="PhoneTextNormalStyle">
        <Setter Property="FontSize" Value="55"/>
        <Setter Property="ForeGround" Value="Black"/>
    </Style>
</Application.Resources>

给文本一个前景色，看。

你的帖子没有任何问题。

希望有帮助!
