XAML'NOT'运营商？

Question

<Button IsEnabled="{Binding (Not IsDisabled)}" />

有没有办法用纯xaml来做,或者我必须通过代码来做到这一点？PS.我问过这个问题我知道我可以像这样创建一个布尔转换器:

<ValueConversion(GetType(Boolean), GetType(Boolean))> 
Public Class BooleanFlagSwitchConverter : Implements IValueConverter

    Public Function Convert(value As Object, targetType As Type, 
            parameter As Object, culture As CultureInfo) As Object 
            Implements IValueConverter.Convert
        Return Not value
    End Function

    Public Function ConvertBack(value As Object, targetType As Type, 
            parameter As Object, ByVal culture As CultureInfo) As Object 
            Implements IValueConverter.ConvertBack
        Return Not value
    End Function

End Class

[ValueConversion(typeof(bool), typeof(bool))]
public class BooleanFlagSwitchConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, 
        CultureInfo culture)
    {
        return !(bool)value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, 
        CultureInfo culture)
    {
        return !(bool)value;
    }
}

它不存在.查看Binding类的属性.没有什么,除了转换器可以做你想要的.
