带有图像的 WPF 单选按钮 [英] WPF radio button with Image

问题描述

我必须创建类似于图片的东西.如果单击其中一个按钮，则其他按钮应变暗.非常感谢！

这就是我需要的

解决方案

当 RadioButton 没有被样式触发器选中时，你可以改变 Opacity

<Style TargetType="RadioButton"><Style.Triggers><Trigger Property="IsChecked" Value="False"><Setter Property="Opacity" Value="0.5"></Setter></触发器></Style.Triggers></风格></RadioButton.Style>

里面的图片可以通过修改Template

来创建

<ControlTemplate TargetType="RadioButton"><!-- 新模板--></控制模板></RadioButton.Template>

可以在

<StackPanel.Resources><Style x:Key="Flag" TargetType="RadioButton"><Style.Triggers><Trigger Property="IsChecked" Value="False"><Setter Property="Opacity" Value="0.5"/></触发器></Style.Triggers><Setter Property="BorderThickness" Value="2"/><Setter 属性="模板"><Setter.Value><ControlTemplate TargetType="RadioButton"><Border BorderThickness="{TemplateBinding BorderThickness}"BorderBrush="{TemplateBinding BorderBrush}"背景=透明"CornerRadius="20"><Image Source="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}"/></边框></控制模板></Setter.Value></Setter></风格></StackPanel.Resources><项目控制><RadioButton Content="../Resources/radio.png" Style="{StaticResource Flag}" BorderBrush="Red" Width="40" Height="40"/><RadioButton Content="../Resources/radio.png" Style="{StaticResource Flag}" BorderBrush="Orange" Width="40" Height="40"/><RadioButton Content="../Resources/radio.png" Style="{StaticResource Flag}" BorderBrush="Green" Width="40" Height="40"/></ItemsControl></StackPanel>

I have to create something similar to the picture. If one of the button is clicked the others should become darker. Thanks a lot!

That's what I need

解决方案

you can change Opacity when RadioButton is not checked via style trigger

<RadioButton.Style>                    
    <Style TargetType="RadioButton">                        
        <Style.Triggers>
            <Trigger Property="IsChecked" Value="False">
                <Setter Property="Opacity" Value="0.5"></Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
</RadioButton.Style>

image inside can be created by modification of Template

<RadioButton.Template>
    <ControlTemplate TargetType="RadioButton">
        <!-- new template -->
    </ControlTemplate>
</RadioButton.Template>

default template can be found here

my primitive template looks like this (i have added 3 radioButtons into ItemsControl, the 2nd is checked)

<StackPanel Grid.Row="0" Grid.Column="1">
    <StackPanel.Resources>
        <Style x:Key="Flag" TargetType="RadioButton">
            <Style.Triggers>
                <Trigger Property="IsChecked" Value="False">
                    <Setter Property="Opacity" Value="0.5"/>
                </Trigger>
            </Style.Triggers>

            <Setter Property="BorderThickness" Value="2"/>

            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="RadioButton">
                        <Border BorderThickness="{TemplateBinding BorderThickness}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                Background="Transparent"
                                CornerRadius="20">                                    
                            <Image Source="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}"/>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </StackPanel.Resources>

    <ItemsControl>
        <RadioButton Content="../Resources/radio.png" Style="{StaticResource Flag}" BorderBrush="Red" Width="40" Height="40"/>
        <RadioButton Content="../Resources/radio.png" Style="{StaticResource Flag}" BorderBrush="Orange" Width="40" Height="40"/>
        <RadioButton Content="../Resources/radio.png" Style="{StaticResource Flag}" BorderBrush="Green" Width="40" Height="40"/>
    </ItemsControl>
</StackPanel>
