将WPF列表框的非活动突出显示颜色设置为活动突出显示颜色 [英] Setting the Inactive Highlight Colour of a WPF ListBox to the Active Highlight Colour

问题描述

我试图制作一个列表框，无论列表框是否具有焦点，突出显示的项目看起来都一样.

I'm trying to make a ListBox where highlighted items look the same regardless of if the ListBox has focus or not.

基本上，我想将SystemColors.ControlBrushKey颜色属性设置为与SystemColors.HighlightBrushKey颜色相同.

Essentially I want to set the SystemColors.ControlBrushKey color property to be the same as the SystemColors.HighlightBrushKey color.

我认为我可以使用以下内容:

I thought I could use the following:

<ListBox>
    <ListBox.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" 
                         Color="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
    </ListBox.Resources>
</ListBox>

但这实际上会引发以下错误:

But this actually throws the following error:

System.Windows.Markup.XamlParseException:设置属性"System.Windows.Media.SolidColorBrush.Color"引发了异常. ---> System.ArgumentException:'#FF3399FF'不是属性'Color'的有效值

System.Windows.Markup.XamlParseException: Set property 'System.Windows.Media.SolidColorBrush.Color' threw an exception. ---> System.ArgumentException: '#FF3399FF' is not a valid value for property 'Color'

如果我设置了Color="#FF3399FF"，它将正常工作.

If I set Color="#FF3399FF" it works fine.

我在做什么错了?

推荐答案

感谢Nicholas W指出正确的方向-这是ListBox的完整代码:

Credit to Nicholas W for pointing me in the right direction - here's the full code for the ListBox:

<ListBox Width="200" Height="200">
    <ListBox.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" 
                         Color="{DynamicResource {x:Static SystemColors.HighlightColorKey}}" />
    </ListBox.Resources>
    <ListBox.ItemContainerStyle>
        <Style>
            <Style.Triggers>
                <Trigger Property="Selector.IsSelected" Value="True">
                    <Setter Property="TextElement.Foreground" Value="White"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListBox.ItemContainerStyle>
    <ListBoxItem IsSelected="True">Item A</ListBoxItem>
    <ListBoxItem>Item B</ListBoxItem>
    <ListBoxItem>Item C</ListBoxItem>
</ListBox>
