wpf radiobutton 组合绑定 事例

以下是一个WPF的RadioButton组合绑定的示例代码：

<StackPanel>
    <RadioButton Content="Option 1" IsChecked="{Binding Path=Option1Checked}" />
    <RadioButton Content="Option 2" IsChecked="{Binding Path=Option2Checked}" />
    <RadioButton Content="Option 3" IsChecked="{Binding Path=Option3Checked}" />
</StackPanel>

在此示例中，三个RadioButton分别绑定到ViewModel中的三个bool属性，例如：

public class MyViewModel : INotifyPropertyChanged
{
    private bool _option1Checked;
    public bool Option1Checked
    {
        get { return _option1Checked; }
        set
        {
            _option1Checked = value;
            OnPropertyChanged(nameof(Option1Checked));
        }
    }

    private bool _option2Checked;
    public bool Option2Checked
    {
        get { return _option2Checked; }
        set
        {
            _option2Checked = value;
            OnPropertyChanged(nameof(Option2Checked));
        }
    }

    private bool _option3Checked;
    public bool Option3Checked
    {
        get { return _option3Checked; }
        set
        {
            _option3Checked = value;
            OnPropertyChanged(nameof(Option3Checked));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

在此示例中，用户可以选择一个选项，ViewModel中对应的属性将自动更新。
