在WPF中悬停文本块时前景色不会改变 [英] Foreground color not change on hover of textblock in WPF

问题描述

大家好，



我在Wpf工作我在文本块上设置Trigger以更改背景和前景但前景颜色不会改变..



请帮助...



我的代码是

 <  样式    x：键  =  LeftHoverBackground    TargetType   =  {x：Type TextBlock} >  
 < ; Setter  Property = TextBlock  .ForegroundValue =＃404041/> 
 < Style  .Triggers> 
 < Trigger  Property =IsMouseOverValue =True> 
 < Setter  Property =TextBlock.ForegroundValue =White> 
 < /   Setter  >  
 <   Setter    属性  = 背景   值  = ＃1A1A1A >  
 <   / Setter  >  
 
 <   / Trigger  >  
 <   / Style.Triggers  >  
 <   / Style  >  

解决方案

您是否在 Textblock 上明确设置了样式？

如果样式有 x：Key 属性然后你需要指定该id使用的样式;

< TextBlock Text =WoohooStyle = {StaticResource LeftHoverBackground}/> 

希望这会有所帮助，

这是我的Xml代码..

hi all,

I am working in Wpf I set Trigger on textblock for Change Background and Foreground But Foreground Color is Not Change..

Please Help...

my code is

<Style x:Key="LeftHoverBackground" TargetType="{x:Type TextBlock}">
            <Setter Property= "TextBlock.Foreground" Value="#404041"/>            
            <Style.Triggers>                
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="TextBlock.Foreground" Value="White">
                    </Setter>
                    <Setter Property="Background" Value="#1A1A1A">
                    </Setter>
                    
                </Trigger>
            </Style.Triggers>
        </Style>

解决方案

Have you set the style explicitly on the Textblock?
If the style has a x:Key attribute then you need to specify the style to be used by that id;

<TextBlock Text="Woohoo" Style="{StaticResource LeftHoverBackground}"/>

Hope this helps,
