更改列表框WPF文字的SelectedItem颜色和高亮区/背景颜色使用C＃ [英] Changing WPF Listbox SelectedItem text color and highlight/background Color using C#

问题描述

我试图更改高亮显示（选择）的颜色，并在运行一个WPF列表框的高亮文本颜色。我曾尝试创建一个样式和应用，如下所示：

 样式S =新样式（typeof运算（列表框））; 
 s.Resources.Add（SystemColors.HighlightBrushKey，Setting.ListSelectedColor）; 
 s.Resources.Add（SystemColors.HighlightTextBrushKey，Setting.ListSelectedTextColor）; 
 lstGames.Style = S; 
  

但这似乎什么也不做。有什么办法来实现这一目标。

编辑：

每建议，我尝试使用DynamicResources来实现这一但到目前为止，这还没有成功无论是。 UserControl.Resources>

DYNAMICRESOURCES

 <：我对这段代码; 
<颜色X：键=ListTextSelectedColor/> 
<颜色X：键=ListSelectedColor/> 
< /UserControl.Resources> 
  

LISTBOX

 <列表框ScrollViewer.Horizo​​ntalScrollBarVisibility =隐藏ScrollViewer.VerticalScrollBarVisibility =隐藏
 NAME =lstGames保证金=20Grid.Row =2Grid.Column =2
的SelectionChanged =lstGames_SelectionChangedGrid.RowSpan =2Grid.ColumnSpan =2
背景={X：空}BorderBrush ={X：空}的SelectionMode =单
字号=18的FontFamily =OCR一个扩展> 
<风格的TargetType =列表框> 
< Style.Resources> 
<的SolidColorBrush X：键={X：静态SystemColors.HighlightBrushKey}颜色={DynamicResource ListSelectedColor}/> 
<的SolidColorBrush X：键={X：静态SystemColors.ControlBrushKey}颜色={DynamicResource ListSelectedColor}/> 
<的SolidColorBrush X：键={X：静态SystemColors.HighlightTextBrushKey}颜色={DynamicResource ListTextSelectedColor}/> 
<的SolidColorBrush X：键={X：静态SystemColors.ControlTextBrushKey}颜色={DynamicResource ListTextSelectedColor}/> 
< /Style.Resources> 
< /样式和GT; 
< /列表框> 
  

投入更多资源在C＃

  this.Resources [ListSelectedColor] = SETING.ListSelectedColor.Color; 
 this.Resources [ListTextSelectedColor] = SETTING.ListSelectedTextColor.Color;

I am trying to change the highlighted(selected) color and the highlighted text color of a wpf listbox at runtime. I have tried creating a style and applying it as follows:

    Style s = new Style(typeof(ListBox));
    s.Resources.Add(SystemColors.HighlightBrushKey, Setting.ListSelectedColor);
    s.Resources.Add(SystemColors.HighlightTextBrushKey, Setting.ListSelectedTextColor);
    lstGames.Style = s;

But this seems to do nothing. Is there any way to achieve this?

EDIT:

Per suggestions, I tried using DynamicResources to achieve this, but so far this has not been successful either. My code for this:

DYNAMICRESOURCES

<UserControl.Resources>
    <Color x:Key="ListTextSelectedColor"/>
    <Color x:Key="ListSelectedColor"/>
</UserControl.Resources>

LISTBOX

        <ListBox ScrollViewer.HorizontalScrollBarVisibility="Hidden" ScrollViewer.VerticalScrollBarVisibility="Hidden" 
             Name="lstGames" Margin="20" Grid.Row="2" Grid.Column="2" 
             SelectionChanged="lstGames_SelectionChanged" Grid.RowSpan="2" Grid.ColumnSpan="2" 
             Background="{x:Null}" BorderBrush="{x:Null}" SelectionMode="Single"
             FontSize="18" FontFamily="OCR A Extended">
        <Style TargetType="ListBox">
            <Style.Resources>
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="{DynamicResource ListSelectedColor}"/>
                <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{DynamicResource ListSelectedColor}"/>
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="{DynamicResource ListTextSelectedColor}"/>
                <SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="{DynamicResource ListTextSelectedColor}"/>
            </Style.Resources>
        </Style>
    </ListBox>

APPLYING RESOURCES IN C#

this.Resources["ListSelectedColor"] = SETING.ListSelectedColor.Color;
this.Resources["ListTextSelectedColor"] = SETTING.ListSelectedTextColor.Color;
