c#-使用MahApps.Metro的WPF CheckComboBox样式

作者:互联网

如何为WPF Extended Toolkit的CheckComboBox设置MahApps.Metro样式?

我的App.xaml包含:

<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />

当我将CheckComboBox放在Window上时,它看起来像这样:

而且简单的ComboBox看起来像这样:

因此样式是不同的.

解决方法:

我根据最新的WPF扩展工具包的CheckComboBox样式创建了简单的MahApps.Metro自定义样式.它可能并不完美,但对我有用.

结果:

仅在主窗口的资源标签中提供以下样式:

<Window.Resources>
    <xctk:InverseBoolConverter x:Key="InverseBoolConverter" />

    <Style BasedOn="{StaticResource {x:Type xctk:SelectorItem}}" TargetType="{x:Type xctk:SelectorItem}">

        <Setter Property="Template">
