我正在创建一个应用程序，在我的主页上我有一个列表，每行都有一个 ToggleSwitch 控件，但该控件没有出现在手机模拟器上。ToggleSwitch 控件的 XAML 如下所示：

<toolkit:ToggleSwitch x:Name="ToggleSwitch" IsChecked="false" Content="Content Goes here" Checked="switch_Unchecked" Unchecked="switch_Unchecked" BorderBrush="black" Background="Black" Width="200"/>

当我单击该代码时，它向我显示：

在此处输入图像描述

所以我相信带有 BorderBrush=black 和 Background=Black 的控件在正确的位置，但它没有出现......有人可以帮助我吗？

拥有这些属性之一，Background或BorderBrush.

你为什么不这样尝试呢？

xml:

<ToggleSwitch x:Name="toggleSwitch1" Header="ToggleSwitch" 
          OnContent="On" OffContent="Off" 
          Toggled="ToggleSwitch_Toggled"/>

private void ToggleSwitch_Toggled(object sender, RoutedEventArgs e)
{
// Add code to perform some action here.
}

看看这个。那是你使用的那个Toolkit还是什么？

希望能帮助到你！

您的网格背景颜色是什么颜色？这也可能有一些问题。尝试为 Toggle Switch 应用以下样式。

 <Grid x:Name="LayoutRoot" Background="White">
    <toolkit:ToggleSwitch Margin="12,0" Content="Live Update" Background="White" Foreground="Black" Style="{StaticResource FixedToggleSwitchStyle}"/>
</Grid>

而且风格是，

<Style x:Key="FixedToggleSwitchButtonStyle" TargetType="toolkitPrimitives:ToggleSwitchButton">
    <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
    <Setter Property="Background" Value="{StaticResource PhoneBackgroundBrush}"/>
    <Setter Property="IsTabStop" Value="False"/>
    <Setter Property="SwitchForeground" Value="{StaticResource PhoneAccentBrush}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="toolkitPrimitives:ToggleSwitchButton">
                <Border x:Name="Root" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CacheMode="BitmapCache" Opacity="{TemplateBinding Opacity}" Padding="{TemplateBinding Padding}">

根据您在 Toggle Switch 中的需要更改背景颜色和前景色。
