将选定和未聚焦的列表框样式更改为不灰显 [英] Change selected and unfocused Listbox style to not be grayed out

问题描述

我有一个非常简单的 WPF 列表框，其中 SelectionMode 设置为 Multiple.

I have a really simple WPF ListBox with SelectionMode set to Multiple.

<ListBox SelectionMode="Multiple" />

当 ListBox 失去焦点时，很难判断选择了什么，因为选择的颜色会从蓝色变为浅灰色.更改此行为以使其保持蓝色的最简单方法是什么?

When the ListBox loses focus it's really hard to tell what's been selected because the selection colour changes from blue to a light grey colour. What's the easiest way of changing this behaviour so that it stays blue?

我知道这可能与 ListItem 的样式有关，但我找不到.

I know it's probably something to do with the ListItem's style, but I can't find where.

干杯.

推荐答案

我在合并的 ResourceDictionary 中使用以下内容做了类似的事情，它可能会对您有所帮助:

I have done something like this using the following in a merged ResourceDictionary, it may help you:

<Style TargetType="ListBoxItem">
    <Style.Resources>
        <!--SelectedItem with focus-->
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="LightBlue" Opacity=".4"/>
        <!--SelectedItem without focus-->
        <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey }" Color="LightBlue" Opacity=".4"/>
    </Style.Resources>
</Style>
