Question

我正在尝试开发设计，如下图所示。我已设法实现如图所示的设计。现在的问题是，当我点击文本框时，它不显示正在键入的字符。虽然通过调试我检查了值正在变量中获取。

代码段：

#if English
#define kUrl @"https://english.example.com"
#else
#define kUrl @"https://world.example.com"
#endif

最好修改控件的默认样式，而不是创建自己的模板。所以你可以使用这个适用于你的场景：

   <TextBox
            Height="54"
            Margin="0"
            VerticalAlignment="Stretch"
            Background="#FFBAC0E0"
            BorderThickness="0"
            Foreground="Aqua"
            Padding="10"
            PlaceholderText="Search here Kindly">
            <TextBox.Style>
                <Style TargetType="TextBox">
                    <Setter Property="MinWidth" Value="{ThemeResource TextControlThemeMinWidth}" />
                    <Setter Property="MinHeight" Value="{ThemeResource TextControlThemeMinHeight}" />
                    <Setter Property="Foreground" Value="{ThemeResource TextBoxForegroundThemeBrush}" />
                    <Setter Property="SelectionHighlightColor" Value="{ThemeResource TextSelectionHighlightColorThemeBrush}" />
