问题描述

在 .NET 4.0 中，ListBox 和 ListView 的高亮显示发生了变化

With .NET 4.0 it appears highlighting of ListBox and ListView has changed

下面是我多年来在 .NET 3.5 的几个地方使用的代码，当不专注时突出显示已停止在 4.0 和 4.5 上工作

Below is code I have used for years in several places on .NET 3.5 and highlight when not focused has stopped working on 4.0 and 4.5

<ListBox.ItemContainerStyle>
    <Style>
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Red"/>
            <!-- Background of selected item when focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Pink"/>
            <!-- Background of selected item when not focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Yellow" />
        </Style.Resources>
    </Style>
</ListBox.ItemContainerStyle>

ListBox SelectedItem 背景

推荐答案

在 .NET 4.0 中有一些新的 SytemColors
这似乎是 .NET 4.0 的方式根据评论，这在 4.5 中发生了变化 - 而不是 4.0.

With .NET 4.0 there are some new SytemColors
This appears to be the .NET 4.0 way According to comment this changed in 4.5 - not 4.0.

<ListBox.ItemContainerStyle>
    <Style>
        <Style.Resources>
            <!-- Foregroud of selected item when focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Red"/>
            <!-- Foregroud of selected item when not focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}" Color="Green"/>
            <!-- Background of selected item when focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Pink"/>
            <!-- Background of selected item when not focussed -->
            <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Yellow" />
        </Style.Resources>
    </Style>
</ListBox.ItemContainerStyle> 

一开始我虽然 ControlBrushKey 的定义变了但是没有变
在这种情况下，ControlBrushKey 的行为似乎发生了变化

At first I though the definition of ControlBrushKey had changed but it has not
It appears the behavior of ControlBrushKey has changed in this situation

注意 GridView 的行为变化
