组选定的项目色的ListView与交流项目的Win7

Question

我有显示所选的项目颜色未在Windows 7（航空）尊重的WPF ListView控件的问题，但工程服务器2008年

第一张照片来自Windows Server 2008机器，点击“培根”选项。然后我在Windows 7上运行相同的程序，并点击“培根”选项。

很明显，我为所选项目设置的背景在Aero主题上没有得到尊重，但我不知道如何处理它。

XAML代码：

<Window x:Class="WPFDriver.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="MainWindow" Height="150" Width="150"> 
    <Window.Resources> 
     <Style TargetType="ListViewItem"> 
      <Setter Property="BorderThickness" Value="0,1,0,0"/> 
      <Setter Property="BorderBrush" Value="Gray" /> 
      <Style.Resources> 
       <!-- set the selected item color --> 
       <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="DeepPink"/> 
      </Style.Resources> 
      <Style.Triggers> 
       <Trigger Property="ItemsControl.AlternationIndex" Value="0"> 
        <Setter Property="Background" Value="{x:Static SystemColors.InfoBrush}" /> 
       </Trigger> 
       <Trigger Property="ItemsControl.AlternationIndex" Value="1"> 
        <Setter Property="Background" Value="{x:Static SystemColors.WindowBrush}"/> 
       </Trigger> 
      </Style.Triggers> 
     </Style> 
    </Window.Resources> 

    <ListView Name="lvItems" AlternationCount="2" ItemsSource="{Binding Path=Joop}"> 
     <ListView.View> 
      <GridView AllowsColumnReorder="True"> 
       <GridViewColumn Header="Widget" DisplayMemberBinding="{Binding Path=Widget}" ></GridViewColumn> 
       <GridViewColumn Header="Coin" DisplayMemberBinding="{Binding Path=Coin}" ></GridViewColumn> 
      </GridView> 
     </ListView.View> 
    </ListView> 
</Window> 

后面的代码：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Data; 
using System.Windows.Documents; 
using System.Windows.Input; 
using System.Windows.Media; 
using System.Windows.Media.Imaging; 
using System.Windows.Navigation; 
using System.Windows.Shapes; 
using System.Collections.ObjectModel; 

namespace WPFDriver 
{ 
    public partial class MainWindow : Window 
    { 
     public class Thing 
     { 
      public string Widget { get; set; } 
      public string Coin { get; set; } 
     } 

     public ObservableCollection<Thing> Joop { get; set; } 

     public MainWindow() 
     { 
      InitializeComponent(); 

      this.DataContext = this; 
      Joop = new ObservableCollection<Thing>(); 

      Joop.Add(new Thing() { Widget = "Code", Coin = "Quarter" }); 
      Joop.Add(new Thing() { Widget = "Bicycle", Coin = "Nickel" }); 
      Joop.Add(new Thing() { Widget = "Bacon", Coin = "Dime" }); 
      Joop.Add(new Thing() { Widget = "A Koda", Coin = "Penny" }); 
     } 
    } 
} 

UPDATE： 由彼得·汉森提出的解决方案一： 在ListView风格，同时添加IsSelected和HighlightBrushKey

<Style TargetType="ListViewItem"> 
    <Setter Property="BorderThickness" Value="0,1,0,0"/> 
    <Setter Property="BorderBrush" Value="Gray" /> 
    <Style.Resources> 
     <!-- set the selected item color (Works for non Aero theme) --> 
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="DeepPink"/> 
    </Style.Resources> 
    <Style.Triggers> 
     <Trigger Property="ItemsControl.AlternationIndex" Value="0"> 
      <Setter Property="Background" Value="{x:Static SystemColors.InfoBrush}" /> 
     </Trigger> 
     <Trigger Property="ItemsControl.AlternationIndex" Value="1"> 
      <Setter Property="Background" Value="{x:Static SystemColors.WindowBrush}"/> 
     </Trigger> 
      <!-- set the selected item color (Works for Win7 Aero theme) --> 
     <Trigger Property="IsSelected" Value="True"> 
      <Setter Property="Background" Value="DeepPink"></Setter> 
     </Trigger> 
    </Style.Triggers> 
</Style> 

Answer 1

您不应该像这样覆盖SystemColors.HighlightBrushKey的值，因为它不是真的可靠。主题可能会以不同的方式获得用于选择的颜色，这就是您现在遇到的情况。

相反，你可以创建一个Trigger侦听到ListViewItem的IsSelected财产和改变颜色，当它是真实的：

<Style TargetType="ListViewItem"> 
    <Style.Triggers> 
     <Trigger Property="IsSelected" Value="True"> 
      <Setter Property="Background" Value="DeepPink" /> 
     </Trigger> 
    </Style.Triggers> 
</Style>
