因此，通过大量浏览，我希望制作一个像单选按钮一样的GroupBox。标题部分将充当子弹。我从这个问题中获取了一些代码
这就是我想要的样子。但我希望将它作为单选按钮。所以我输入了这段代码（请注意，我现在只做了一周或两周的WPF）
<Style TargetType="{x:Type RadioButton}" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<BulletDecorator>
<BulletDecorator.Bullet>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Border x:Name="SelectedBorder"
Grid.Row="0"
Margin="4"
BorderBrush="Black"
BorderThickness="1"
Background="#25A0DA">
<Label x:Name="SelectedLabel" Foreground="Wheat">
<ContentPresenter Margin="4" />
</Label>
</Border>
<Border>
</Border>
</Grid>
</BulletDecorator.Bullet>
</BulletDecorator>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="true">
<Setter TargetName="SelectedBorder" Property="Background" Value="PaleGreen"/>
<Setter TargetName="SelectedLabel"
Property="Foreground"
Value="Black" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我有一种感觉，我可以在网格的第二行添加标签，但后来我不知道如何访问它。我在Window.Resources部分的测试项目中有该模板（我计划将其移动到我的主项目中的资源字典） 我的窗口的xaml就是这个
<Grid>
<GroupBox Name="grpDoor" Margin ="8" Grid.Row="0" Grid.Column="0">
<GroupBox.Header>
WPF RadioButton Template
</GroupBox.Header>
<StackPanel Margin ="8">
<RadioButton FontSize="15" Content="Dhaka" Margin="4" IsChecked="False"/>
<RadioButton FontSize="15" Content="Munshiganj" Margin="4" IsChecked="True" />
<RadioButton FontSize="15" Content="Gazipur" Margin="4" IsChecked="False" />
</StackPanel>
</GroupBox>
</Grid>
然后我希望这样的事情（虽然不知道我怎么做）
<Grid>
<GroupBox Name="grpDoor" Margin ="8" Grid.Row="0" Grid.Column="0">
<GroupBox.Header>
WPF RadioButton Template
</GroupBox.Header>
<StackPanel Margin ="8">
<RadioButton FontSize="15"
Content="Dhaka"
Margin="4"
IsChecked="False">
<RadioButton.Description>
This is a description that would show under my Header
</RadioButton.Description>
</RadioButton>
<RadioButton FontSize="15"
Content="Munshiganj"
Margin="4"
IsChecked="True">
<RadioButton.Description>
This is a description that would show under my Header
</RadioButton.Description>
</RadioButton>
<RadioButton FontSize="15"
Content="Gazipur"
Margin="4"
IsChecked="False">
<RadioButton.Description>
This is a description that would show under my Header
</RadioButton.Description>
</RadioButton>
</StackPanel>
</GroupBox>
</Grid>

根据您的澄清，这是一个非常简单的示例，其中RadioButton看起来像一个GroupBox。
<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
<local:SimpleViewModel/>
</Window.DataContext>
<Window.Resources>
<DataTemplate DataType="{x:Type local:SimpleOption}">
<RadioButton GroupName="choice" IsChecked="{Binding Path=IsSelected, Mode=TwoWay}">
<RadioButton.Template>
<ControlTemplate TargetType="{x:Type RadioButton}">
<GroupBox x:Name="OptionBox" Header="{Binding Path=DisplayName, Mode=OneWay}">
<TextBlock Text="{Binding Path=Description, Mode=OneWay}"/>
</GroupBox>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding Path=IsSelected, Mode=OneWay}" Value="True">
<Setter TargetName="OptionBox" Property="Background" Value="Blue"/>
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</RadioButton.Template>
</RadioButton>
</DataTemplate>
</Window.Resources>
<Grid>
<ListBox ItemsSource="{Binding Path=Options, Mode=OneWay}"/>
</Grid>
</Window>
public class SimpleViewModel
{
public SimpleViewModel()
{
Options = new ObservableCollection<SimpleOption>();
var _with1 = Options;
_with1.Add(new SimpleOption {
DisplayName = "Dhaka",
Description = "This is a description for Dhaka."
});
_with1.Add(new SimpleOption {
DisplayName = "Munshiganj",
Description = "This is a description for Munshiganj.",
IsSelected = true
});
_with1.Add(new SimpleOption {
DisplayName = "Gazipur",
Description = "This is a description for Gazipur."
});
}
public ObservableCollection<SimpleOption> Options { get; set; }
}
public class SimpleOption : INotifyPropertyChanged
{
public string DisplayName {
get { return _displayName; }
set {
_displayName = value;
NotifyPropertyChanged("DisplayName");
}
}
private string _displayName;
public string Description {
get { return _description; }
set {
_description = value;
NotifyPropertyChanged("Description");
}
}
private string _description;
public bool IsSelected {
get { return _isSelected; }
set {
_isSelected = value;
NotifyPropertyChanged("IsSelected");
}
}
private bool _isSelected;
private void NotifyPropertyChanged(string propertyName)
{
if (PropertyChanged != null) {
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public event PropertyChangedEventHandler INotifyPropertyChanged.PropertyChanged;
public delegate void PropertyChangedEventHandler(object sender, PropertyChangedEventArgs e);
}

我会使用自定义附加属性来执行此操作。这样，您可以从ViewModel绑定它，或直接在XAML中应用它。
首先，在Style程序集中创建一个新类：
public static class RadioButtonExtender
{
public static readonly DependencyProperty DescriptionProperty = DependencyProperty.RegisterAttached(
"Description",
typeof(string),
typeof(RadioButtonExtender),
new FrameworkPropertyMetadata(null));
[AttachedPropertyBrowsableForType(typeof(RadioButton))]
public static string GetDescription(RadioButton obj)
{
return (string)obj.GetValue(DescriptionProperty);
}
public static void SetDescription(RadioButton obj, string value)
{
obj.SetValue(DescriptionProperty, value);
}
}
您的样式Bullet会发生变化，因此标签为：
<Label x:Name="SelectedLabel"
Foreground="Wheat"
Content="{Binding (prop:RadioButtonExtender.Description), RelativeSource={RelativeSource TemplatedParent}} />
然后您可以在最终的XAML中使用它：
<RadioButton FontSize="15"
Content="Dhaka"
Margin="4"
IsChecked="False">
<prop:RadioButtonExtender.Description>
This is a description that would show under my Header
</prop:RadioButtonExtender.Description>
</RadioButton>
作为额外的好处，由于您在单独的程序集中创建Style，因此您可以创建custom XAML namespace以便更轻松地使用您的财产。
