C# 如何在WPF multibind'；中获取按钮的当前启用/禁用状态；转换为'；方法

我的程序有这种多重绑定

<MultiBinding Converter="{StaticResource myConverter}" Mode="OneWay">
<Binding Path="SelectedItems.Count"/>
<Binding Path="EffectiveStyleContext.Selection"/>
</MultiBinding>

---

您必须将控件本身传递到

值转换器

您修改的

Xaml

将

<MultiBinding Converter="{StaticResource myConverter}" Mode="OneWay">
    <Binding RelativeSource="{RelativeSource Self}"/>
    <Binding Path="SelectedItems.Count"/>
    <Binding Path="EffectiveStyleContext.Selection"/>
</MultiBinding>

---

也可以直接绑定到属性本身：

<Binding Path="IsEnabled" RelativeSource="{RelativeSource Self}" />

---

实际上，我认为这更可取，因为启用状态改变时，多重绑定不会得到更新。我想知道为什么不能将converterParameter用于相同的事情？

public class MyConverter : IMultiValueConverter
{  
    public object Convert(object[] values, System.Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        var control = values[0] as FrameworkElement;
        var value1 = values[1] as int;

        // write your logic here.          
    }

    public object[] ConvertBack(object value, System.Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
    {
        return throw new System.NotImplementedException();;
    }
}

<Binding Path="IsEnabled" RelativeSource="{RelativeSource Self}" />
