UWP XAML文本框字体颜色不会改变

xaml uwp

UWP XAML文本框字体颜色不会改变,xaml,uwp,Xaml,Uwp,也许我错过了什么。。。但是我的文本框的文本输入总是黑色的。我以为你只需要改变前景属性，文本颜色就会改变这是我的文本框。在本例中，我还需要做什么才能使字体变为蓝色？还有一个IsColorFontEnabled属性。。。但这并没有改变任何事情 <TextBox TextWrapping="Wrap" AcceptsReturn="True" FontSize="{ThemeResource TextStyleLargeFontSize}" Foregro

也许我错过了什么。。。但是我的文本框的文本输入总是黑色的。我以为你只需要改变前景属性，文本颜色就会改变

这是我的文本框。在本例中，我还需要做什么才能使字体变为蓝色？还有一个IsColorFontEnabled属性。。。但这并没有改变任何事情

<TextBox TextWrapping="Wrap" AcceptsReturn="True" 
         FontSize="{ThemeResource TextStyleLargeFontSize}"
         Foreground="Blue" ScrollViewer.VerticalScrollBarVisibility="Auto"/>

在这种情况下，前台属性仅在文本框不对焦时起作用，为其指定固定的宽度和高度，在框内放置一些文本，当您在框外单击时，颜色将变为蓝色

如何改变聚焦状态？获取默认的文本框样式：

复制并粘贴到控件的资源中，用x:Key命名，然后应用到文本框。现在一切都应该是一样的。找到一个专注的状态（）并将其更改为：

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentElement"
                                           Storyboard.TargetProperty="Foreground">
                                            <DiscreteObjectKeyFrame KeyTime="0" Value="Blue" />

或者，如果您希望继承它并对聚焦状态和非聚焦状态具有相同的值：

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentElement"
                                           Storyboard.TargetProperty="Foreground">
                                            <DiscreteObjectKeyFrame KeyTime="0" Value="{TemplateBinding Foreground}" />
                                        </ObjectAnimationUsingKeyFrames>

毕竟，它可能看起来像：

<Page.Resources>
    <Style TargetType="TextBox" x:Key="TestStyle">
        <Setter Property="MinWidth" Value="{ThemeResource TextControlThemeMinWidth}" />
        <Setter Property="MinHeight" Value="{ThemeResource TextControlThemeMinHeight}" />
