WPF组合框颜色 [英] WPF combobox colors

问题描述

我在应用程序中通过将 Style 添加到App.xaml来更改所有 ComboBox ：

I'm changing the look of all ComboBoxes in my application by adding this Style to App.xaml:

    <Style TargetType="ComboBox">
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Background" Value="#303030"/>
        <Setter Property="BorderBrush" Value="#000000"/>
    </Style>

有两种颜色，我无法设置：

There are two colors that I haven't been able to set:

1）背景颜色 IsEnabled = false

2）当鼠标位于 ComboBox 上方时，突出显示 Background

2) the highlight Background color when the mouse is over the ComboBox.

如何更改这两种颜色？

推荐答案

您想要检查样式触发器。还需要重写ItemContainerStyle以摆脱默认浅蓝色选择颜色

You want to check Style Triggers . Also need to override the ItemContainerStyle to get rid of the default light blue selection color

<Style.Triggers>
  <Trigger Property="IsMouseOver" Value="true">
    <Setter Property="Background" Value="SomeColor" />
  </Trigger>
  <Trigger Property="IsEnabled" Value="false">
    <Setter Property="Background" Value="SomeOtherColor" />
  </Trigger>
</Style.Triggers>
