UWP自定义文本框样式

uwp

UWP自定义文本框样式,uwp,Uwp,我目前正在对一个现有的UWP项目进行重新设计，其中需要实现一些与以前略有不同的TextBox控件。Header属性应该显示在文本框中，并且应该有一些其他的小调整，比如CornerRadius等等。这应该相对容易（或者我认为是这样）。根据我在UWP样式设计方面的经验（无可否认，有点有限），经过一些搜索，我得出结论，我最好的方法是创建一个新的样式，目标是TextBox，这样我可以指定哪个框将以这种方式工作，其余的保持不变 我创建了一个自定义样式，BorderElement从第0行开始，跨越两行，通过

我目前正在对一个现有的UWP项目进行重新设计，其中需要实现一些与以前略有不同的
TextBox
控件。Header属性应该显示在
文本框中
，并且应该有一些其他的小调整，比如
CornerRadius
等等。这应该相对容易（或者我认为是这样）。根据我在UWP样式设计方面的经验（无可否认，有点有限），经过一些搜索，我得出结论，我最好的方法是创建一个新的样式，目标是
TextBox
，这样我可以指定哪个框将以这种方式工作，其余的保持不变

我创建了一个自定义样式，
BorderElement
从第0行开始，跨越两行，通过从通用XAML文件复制
TextBox
的模板来包围标题和输入文本。看起来是这样的：

<Style x:Key="InlineHeaderTextBox" TargetType="TextBox">

        <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False" />
