为切换按钮提供默认文本 wpf c#
Give the togglebutton a default text wpf c#
我有一个如下所示的这种样式的切换按钮，切换按钮工作得很好，但我想在打开 MainWindow 时为切换按钮设置一个默认文本，它应该显示在 false 状态下，而不是禁用
仅当我对其进行操作（使其打开或关闭）时，切换按钮才会显示文本值，它会显示文本，但默认情况下，用户似乎已被禁用（参见图片）
启动应用后:
设置为：
设置为关闭：
问题是当我 运行 在点击 Toggle 按钮之前应用程序时，屏幕上显示的是 Tooglebutton 被禁用，我需要将此控件初始化为状态“OFF”，
可能吗？
我该怎么做？

更新 2（测试 Jason 的解决方案）。
这是我得到的：
由于您的颜色是通过对 IsChecked 状态变化作出反应来设置的，因此您只需要您的初始值与 false 状态相匹配。将边框颜色设置为关闭颜色（红色）而不是白色。那应该可以满足您的需求。
<Setter.Value>

<Grid x:Name="toggleSwitch">
<Border x:Name="Border" CornerRadius="10"
Background="#C2283B"
Width="80" Height="25">
...
</Setter.Value>
同时将“打开”文本的默认不透明度设置为 0 以防止其显示。
<TextBlock x:Name="txtOn" Text="ON" Opacity="0" Margin="40 0 0 0" VerticalAlignment="Center" FontWeight="DemiBold" Foreground="White" HorizontalAlignment="Left" FontSize="12" />
