更改按钮背景未启用时，

问题描述

我需要改变我的按钮的背景（如的SolidColorBrush例如）仅在未启用（ IsEnabled ==假）。照片我该怎么办？

我是否修改使用XAML或者我可以以编程方式做这项工作的一个按钮风格？什么是正确的XAML code，当未启用，只改变背景？

我尝试以下XAML code，但它没有任何效果：

 ＆LT;按钮和GT;
＆LT; Button.Style＆GT;
    ＆LT;风格的TargetType =按钮＆GT;
        ＆LT; Style.Triggers＆GT;
            ＆LT;触发属性=IsEnabledVALUE =FALSE＆GT;
                ＆LT; setter属性=背景值=红＆GT;＆LT; /二传手＆GT;
            ＆LT; /触发＆GT;
        ＆LT; /Style.Triggers>
    ＆LT; /样式和GT;
＆LT; /Button.Style>
＆LT; /按钮＆GT;
 

解决方案

您可以通过编辑模板更改背景。你会发现按钮的。

在触发 IsEnabled 您可以简单地添加这样的：

 ＆LT; setter属性=背景VALUE ={StaticResource的DisabledBackgroundBrush}/＆GT;
 

修改：
试试这个话;

 ＆LT; Window.Resources＆GT;
    ＆LT;风格的TargetType ={X：类型按钮}＆GT;
        ＆LT; setter属性=模板＆GT;
            ＆LT; Setter.Value＆GT;
                ＆LT;的ControlTemplate的TargetType =按钮＆GT;
                    ＆LT; BORDER X：NAME =叠加CornerRadius =2＆GT;
                        ＆lt;内容presenter /＆GT;
                    ＆LT; /边框＆GT;
                    ＆LT; ControlTemplate.Triggers＆GT;
                        ＆LT;触发属性=IsEnabledVALUE =false的＆GT;
                            ＆LT;二传手的TargetName =叠加属性=背景VALUE =红/＆GT;
                        ＆LT; /触发＆GT;
                    ＆LT; /ControlTemplate.Triggers>
                ＆LT; /控件模板＆GT;
            ＆LT; /Setter.Value>
        ＆LT; /二传手＆GT;
    ＆LT; /样式和GT;
＆LT; /Window.Resources>
＆LT;＆StackPanel的GT;
    ＆LT;按钮内容=按钮IsEnabled =FALSE/＆GT;
＆LT; / StackPanel的＆GT;
 

只要改变它来满足您的需求。

I need to change my Button background (as SolidColorBrush for example) only when it is not enabled (IsEnabled == false).
How can I do?

Have I to modify the Button Style using the XAML or can I do this work programmatically? What is the correct XAML code, to change only the Background when it is not enabled?

I tried the following XAML code but it has no effect:

<Button>
<Button.Style>
    <Style TargetType="Button">
        <Style.Triggers>
            <Trigger Property="IsEnabled" Value="False">
                <Setter Property="Background" Value="Red"></Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
</Button.Style>
</Button>

解决方案

You can change the background by editing the template. You'll find the default template for Button here.

In the trigger for IsEnabled you can simply add something like this:

<Setter Property="Background" Value="{StaticResource DisabledBackgroundBrush}"/>

EDIT:Try this instead then;

<Window.Resources>
    <Style TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border x:Name="Overlay" CornerRadius="2">
                        <ContentPresenter/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter TargetName="Overlay" Property="Background" Value="Red"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
<StackPanel>
    <Button Content="Button" IsEnabled="False"/>
</StackPanel>

Just change it to suit your needs.
