How Design a style in WPF radiobutton like checkbox
提问by Ahad aghapour
I want to have a radiobutton similar to checkbox, so I define a style in Dictionary file like:
我想要一个类似于复选框的单选按钮，所以我在字典文件中定义了一个样式，如：
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfCheckBoxLikeRadiobutton">
<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid>
<CheckBox
IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=IsChecked, Mode=TwoWay}"
IsHitTestVisible="False" />
<CheckBox
IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=IsChecked, Mode=TwoWay}" Opacity="0"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
and merge it in app.xaml file like this
并像这样将其合并到 app.xaml 文件中
<Application x:Class="WpfCheckBoxLikeRadiobutton.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfCheckBoxLikeRadiobutton"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dictionary1.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
and then use it in my window
然后在我的窗口中使用它
<GroupBox Margin="5" Padding="5">
<StackPanel >
<CheckBox Content="this is checkbox" />
<RadioButton Content="this is first radio button" Style="{DynamicResource MyRadioButton}"/>
<RadioButton Content="this is Second radio button" Style="{DynamicResource MyRadioButton}"/>
<RadioButton Content="this is third radio button" Style="{DynamicResource MyRadioButton}"/>
</StackPanel>
</GroupBox>
but after assigning style for radiobutton, that content will disappear. What is the wrong with my style?
但是在为单选按钮指定样式后，该内容将消失。我的风格有什么问题？

It happens because you ignore content of your control in you ControlTemplate. Your style should look like this:
它的发生是因为你忽略了你控制的内容ControlTemplate。你的风格应该是这样的：
<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid>
<CheckBox
IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=IsChecked, Mode=TwoWay}"
IsHitTestVisible="False" Content="{TemplateBinding Content}" />
<CheckBox
IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=IsChecked, Mode=TwoWay}"
Content="{TemplateBinding Content}" Opacity="0"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>

I think you can even do more simple and make it look better, just right click --> EditStyle and replace every ellipse with rectangle in the template. There are a lot of animations you won't loose this way.
我认为您甚至可以做得更简单并使其看起来更好，只需右键单击 --> EditStyle 并将模板中的每个椭圆替换为矩形。有很多动画你不会以这种方式丢失。
This is what I did it looks nice, you can also copy the "CheckIcon" from the checkbox style to make it looks exactly like a checkbox if you want to.
这就是我所做的看起来不错，如果您愿意，您还可以从复选框样式中复制“CheckIcon”，使其看起来完全像一个复选框。

Then merge above style into Verbon's style :
然后将上面的样式合并到 Verbon 的样式中：
<Grid>
<CheckBox IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsChecked, Mode=TwoWay}" IsHitTestVisible="False" Content="{TemplateBinding Content}" Style="{StaticResource CheckBoxRadioButtonStyle}"/>
<CheckBox IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsChecked, Mode=TwoWay}" Content="{TemplateBinding Content}" Opacity="0" Style="{StaticResource CheckBoxRadioButtonStyle}"/>
</Grid>
