更改选定而散列表框风格不被变灰 [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的ListBox用的SelectionMode设置为多。

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

<ListBox SelectionMode="Multiple" />

当ListBox中失去焦点这真的很难说什么被选中，因为从蓝色选择的颜色变为浅灰色。有什么改变，使其保持蓝色这种行为的最简单的方法是什么？

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?

我知道这可能是与该列表项的风格，但我找不到在哪里。

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

我做了这样的事情用一个合并的ResourceDictionary以下，它可以帮助你：

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.ControlBrushKey}" Color="LightBlue" Opacity=".4"/>
    </Style.Resources>
</Style>
