我如何设定“残疾人”的风格?我的自定义用户控件的状态?我不清楚如何设置自定义用户控件的各个部分的样式。例如,我的自定义用户控件由几个组件组成。那么如何在全局样式表中定位控件的特定部分?请记住,如果它再次启用,我希望它恢复原来的颜色。
这是我的自定义用户控制代码......

样式表
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Trigger Property="IsEnabled" Value="False">

最好为每个Style
创建或覆盖Control
。它为您提供了Controls
来自代码隐藏的更改样式的灵活性,这是一个关注点的分离。
例如,让我们看一下TextBlock
的样式,它的样式取决于IsMouseOver
或IsEnabled
条件:
在App.xaml文件中:
<Application x:Class="UWPWpfApplication.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<Style TargetType="TextBlock" x:Key="VNodeTextBlock">
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="FontSize" Value="8"/>
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="Red" />
</Trigger>
<Trigger Property="IsEnabled" Value="True">
<Setter Property="Foreground" Value="Green" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="FontSize" Value="20" />
</Trigger>
</Style.Triggers>
</Style>
</Application.Resources>
</Application>
表格:
<TextBlock Text="Hello World!:)" Style="{StaticResource VNodeTextBlock}"/>
