Question

如何在代码中以编程方式实现这一行XAML？（因为我需要动态创建单选按钮，但它们具有绑定功能）

<RadioButton IsChecked="{Binding Path=Mode, Converter={StaticResource enumBooleanConverter}, ConverterParameter=Proxy}">Proxy</RadioButton>

到目前为止，我已经到了这里（见下文），但现在我正在努力解决如何将绑定连接起来。我做了一个猜测/假设我应该使用Binding类...

    foreach (KeyValuePair<int, string> @interface in interfaces)
    {
        // RadioButton IsChecked="{Binding Path=Mode, Converter={StaticResource enumBooleanConverter}, ConverterParameter=Proxy, UpdateSourceTrigger=PropertyChanged , Mode=TwoWay}">Proxy</RadioButton>

        // Create Radio Button
        var newRb = new RadioButton();
        newRb.Name = "I" + @interface.Key.ToString();
        newRb.GroupName = "InterfaceGroup";
        newRb.Content = @interface.Value;

        // Binding
        var binding = new Binding();
        binding.Source = "Interface";
        binding.Converter = new RadioBoolToIntConverter();
        binding.ConverterParameter = @interface.Key;

        // STUCK HERE - RE HOW TO GET THE BINDING TO BE APPLIED TO THE RADIO BUTTON

        InterfacesRadioButtons.Children.Add(newRb);
    }

对于后台具有依赖项对象的模型类：

public class ConfigWindowViewModel : DependencyObject
{
    // Interface Number 
    public int Interface
    {
        get { return (int)GetValue(InterfaceProperty); }
        set { SetValue(InterfaceProperty, value); }
    }
    public static readonly DependencyProperty InterfaceProperty =
        DependencyProperty.Register("Interface", typeof(int), typeof(ConfigWindowViewModel), new UIPropertyMetadata(0));

   }

Answer 1

newRb.SetBinding(RadioButton.IsCheckedProperty, binding);

可替换地：

BindingOperations.SetBinding(radioButton, RadioButton.IsCheckedProperty, binding);
