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:
<按钮和GT;
< Button.Style>
<风格的TargetType =按钮>
< Style.Triggers>
<触发属性=IsEnabledVALUE =FALSE>
< setter属性=背景值=红>< /二传手>
< /触发>
< /Style.Triggers>
< /样式和GT;
< /Button.Style>
< /按钮>
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:
< setter属性=背景VALUE ={StaticResource的DisabledBackgroundBrush}/>
修改:
试试这个话;
< Window.Resources>
<风格的TargetType ={X:类型按钮}>
< setter属性=模板>
< Setter.Value>
<的ControlTemplate的TargetType =按钮>
< BORDER X:NAME =叠加CornerRadius =2>
<内容presenter />
< /边框>
< ControlTemplate.Triggers>
<触发属性=IsEnabledVALUE =false的>
<二传手的TargetName =叠加属性=背景VALUE =红/>
< /触发>
< /ControlTemplate.Triggers>
< /控件模板>
< /Setter.Value>
< /二传手>
< /样式和GT;
< /Window.Resources>
<&StackPanel的GT;
<按钮内容=按钮IsEnabled =FALSE/>
< / StackPanel的>
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>
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.
