设置背景颜色或WPF（4.0）列表框 - Windows 8的 [英] Setting Background Color or WPF (4.0) ListBox - Windows 8

问题描述

我试图设置所选ListBoxItem的背景色为白色，而不是系统颜色。我读了我能找到这里SO和遵循，或相信也跟着那里的建议（<一个href=\"http://stackoverflow.com/questions/2138200/change-background-color-for-selected-listbox-item/2138237#2138237\">Change背景颜色为选定的列表框项，<一个href=\"http://stackoverflow.com/questions/3111763/wpf-how-to-change-the-listbox-selected-item-text-color-when-the-list-box-loses-f\">WPF如何更改列表框中选定项的文字颜色，当列表框失去焦点，<一个href=\"http://stackoverflow.com/questions/698830/change-selected-and-unfocused-listbox-style-to-not-be-grayed-out\">Change选择而散列表框风格不被变灰以及其他）。

I am attempting to set the background color of a selected ListBoxItem to be white rather than the system color. I have read what I could find here on SO and have followed, or believed to have followed the recommendations there (Change background color for selected ListBox item, WPF How to change the listbox selected item text color when the list box loses focus, Change selected and unfocused Listbox style to not be grayed out, and others).

似乎都被HighlightBrush和ControlBrush设置为透明的，所选项目要解决的问题。我有以下XAML和它正确地设置字体颜色，但backgroound是默认透明的蓝色无论刷设置。我还是有点WPF小白，所以我一定是简单的东西在这里。

All seem to solve the problem by setting the HighlightBrush and ControlBrush to Transparent for the selected item. I have the following XAML and it sets the font color properly, but the backgroound is the default transparent blue regardless of the brush settings. I am still a bit of a WPF noob, so I must be missing something simple here.

<ListBox Width="Auto" Height="Auto" Grid.Column="0" BorderThickness="0" Background="#FFF3F3F3" xmlns:sys="clr-namespace:System;assembly=mscorlib">
    <ListBox.ItemsSource>
       <x:Array Type="{x:Type sys:String}">
          <sys:String>String 1</sys:String>
          <sys:String>String 2</sys:String>
          <sys:String>String 3</sys:String>
          <sys:String>String 4</sys:String>
       </x:Array>
    </ListBox.ItemsSource>
    <ListBox.ItemContainerStyle>
       <Style TargetType="ListBoxItem" BasedOn="{StaticResource {x:Type ListBoxItem}}">
          <Style.Resources>
             <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
             <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
          </Style.Resources>
          <Setter Property="HorizontalContentAlignment" Value="Stretch" />
          <Setter Property="FontSize" Value="16"/>
          <Setter Property="Foreground" Value="#999999"/>
          <Style.Triggers>
             <Trigger Property="IsSelected" Value="True" >
                <Setter Property="Background" Value="White" />
                <Setter Property="Foreground" Value="Black" />
             </Trigger>
          </Style.Triggers>
       </Style>
    </ListBox.ItemContainerStyle>
    <ListBox.ItemTemplate>
       <DataTemplate>
          <TextBlock Text="{Binding}" HorizontalAlignment="Right" Margin="0,0,8,0" Background="Transparent"/>
       </DataTemplate>
    </ListBox.ItemTemplate>
 </ListBox>

我想AP preciate在正确的方向蹭任何

I would appreciate any nudges in the right direction.

修改

看完第一个答案，这为他们工作有轻微的改变后，我花了，我一直在我的Windows 8机器上开发应用并在Windows 7虚拟机执行它和它的工作如预期。什么需要改变得到这个到Windows 8的机器，以及在Windows 7上运行任何想法？

After reading the first answer that it worked for them with a slight change, I took the application that I have been developing on my Windows 8 machine and executed it in a Windows 7 VM and it worked as expected. Any ideas on what needs to change to get this to work on a Windows 8 machine as well as a Windows 7?

推荐答案

这些职位渐渐过时的Windows 8。

Those posts are getting outdated for Windows-8.

在Windows的8出于某种原因，微软不希望人们编辑其默认风格的这么容易，或用刷过程。

In Windows-8 for some reason Microsoft don't want people editing their Default Style's so easily or something with a Brush over-ride.

ListBoxItem的默认风格从VS有这样的选择会触发：

ListBoxItem default Style from VS has this for selection triggers:

<MultiTrigger>
  <MultiTrigger.Conditions>
    <Condition Property="Selector.IsSelectionActive"
                Value="False" />
    <Condition Property="IsSelected"
                Value="True" />
  </MultiTrigger.Conditions>
  <Setter TargetName="Bd"
          Property="Background"
          Value="#3DDADADA" />
  <Setter TargetName="Bd"
          Property="BorderBrush"
          Value="#FFDADADA" />
</MultiTrigger>
<MultiTrigger>
  <MultiTrigger.Conditions>
    <Condition Property="Selector.IsSelectionActive"
                Value="True" />
    <Condition Property="IsSelected"
                Value="True" />
  </MultiTrigger.Conditions>
  <Setter TargetName="Bd"
          Property="Background"
          Value="#3D26A0DA" />
  <Setter TargetName="Bd"
          Property="BorderBrush"
          Value="#FF26A0DA" />
</MultiTrigger>

触发为选择状态不再申请画笔，我们可以过骑容易，但一成不变的颜色。因此，要修改它，你将需要导出模板，并修改触发那里。到白色

这是VS2012的Windows-8 ListBoxItem的

          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

如果您修改这些触发器：

if you modify those triggers to:

<MultiTrigger>
  <MultiTrigger.Conditions>
    <Condition Property="Selector.IsSelectionActive"
                Value="False" />
    <Condition Property="IsSelected"
                Value="True" />
  </MultiTrigger.Conditions>
  <Setter TargetName="Bd"
          Property="Background"
          Value="White" />
  <Setter TargetName="Bd"
          Property="BorderBrush"
          Value="White" />
</MultiTrigger>
<MultiTrigger>
  <MultiTrigger.Conditions>
    <Condition Property="Selector.IsSelectionActive"
                Value="True" />
    <Condition Property="IsSelected"
                Value="True" />
  </MultiTrigger.Conditions>
  <Setter TargetName="Bd"
          Property="Background"
          Value="White" />
  <Setter TargetName="Bd"
          Property="BorderBrush"
          Value="White" />
</MultiTrigger>
