为什么按钮背景在ispressed为true时默认为灰色?

我有一个简单的问题。使用ispressed触发器,我希望能够将按钮的背景色设置为默认灰色以外的其他颜色。以下是未按下按钮时的外观

下面是单击时的外观

这是按钮的触发器。我知道触发器是正确的,因为当它被点击时,按钮边缘的发光效果。我也知道画笔是正确的,因为我试着把它作为背景画笔来看看它是什么样子的。

<style.triggers>
<trigger property=“ismouseover”value=“true”>
<setter property=“background”value=“dynamicResource buttonHoverBrush”/>
<setter property=“bitmapeffect”value=“dynamicResource buttonHoverGlow”/>gt;
</trigger>
&!--这是正在工作的触发器,但背景色不会更改-->
<trigger property=“ispressed”value=“true”>
<setter property=“bitmapeffect”value=“dynamicResource buttonHoverGlow”/>gt;
<setter property=“background”value=“dynamicResource buttonPressedBrush”“/>
</trigger>
</style.triggers>
< /代码> 

这里是整个样式,如您所见,它是应用于应用程序中所有按钮的默认样式。


<style targetType=“button”>
<setter property=“background”value=“dynamicResource buttonBrush”/>gt;
<setter property=“foreground”value=“black”/>
<style.triggers>
<trigger property=“ismouseover”value=“true”>
<setter property=“background”value=“dynamicResource buttonHoverBrush”/>
<setter property=“bitmapeffect”value=“dynamicResource buttonHoverGlow”/>gt;
</trigger>
<trigger property=“ispressed”value=“true”>
<setter property=“bitmapeffect”value=“dynamicResource buttonHoverGlow”/>gt;
<setter property=“background”value=“dynamicResource buttonPressedBrush”“/>
</trigger>
</style.triggers>
&风格/风格;
< /代码> 

这里是最终解决方案(感谢所有帮助过的人)



为常规按钮创建控件模板并执行一些数据绑定:

<controlTemplate targetType=“Button”x:key=“ButtonControlTemplate”>
<border background=“模板绑定背景”
borderthickness=“模板绑定borderthickness”
borderBrush=“模板绑定borderBrush”
cornerradius=“3”>
格栅& GT;
<ContentPresenter ContentSource=“模板绑定内容”
contenttemplate=“模板绑定contenttemplate”
VerticalAlignment=“模板绑定VerticalContentAlignment”
HorizontalSignment=“模板绑定HorizontalContentAlignment”/>
和/格栅& GT;
&边界/gt;
</controltemplate>

将控件模板添加到样式:

<style targetType=“button”>
<setter property=“background”value=“dynamicResource buttonBrush”/>gt;
<setter property=“foreground”value=“black”/>
<setter property=“template”value=“dynamicResource buttonControlTemplate”“/>
<setter property=“borderthickness”value=“1”/>
<style.triggers>
<trigger property=“ismouseover”value=“true”>
<setter property=“background”value=“dynamicResource buttonHoverBrush”/>
<setter property=“bitmapeffect”value=“dynamicResource buttonHoverGlow”/>gt;
</trigger>
<trigger property=“ispressed”value=“true”>
<setter property=“bitmapeffect”value=“dynamicResource buttonHoverGlow”/>gt;
<setter property=“background”value=“dynamicResource buttonPressedBrush”“/>
</trigger>
</style.triggers>
&风格/风格;



注意:BorderThickness默认为1,否则它不会显示将按钮的r改为默认的灰色。这是不按按钮时的样子



这是点击时的样子

        </Trigger>
        <!-- This is the trigger which is working but the background color wont change -->
        <Trigger Property="IsPressed" Value="True">
            <Setter Property="BitmapEffect" Value="{DynamicResource ButtonHoverGlow}"/>
