关于WPF的bool值反向绑定的内容

关于WPF实现方向绑定选中的要求

反向选择的相关要求

[ValueConversion(typeof(bool), typeof(bool))]
public class InverseBooleanConverter : IValueConverter
{
    #region IValueConverter Members

    public object Convert(object value, Type targetType, object parameter,
         System.Globalization.CultureInfo culture)
    {
        if (targetType != typeof(bool))
            throw new InvalidOperationException("The target must be a boolean");

        return !(bool)value;
    }

    public object ConvertBack(object value, Type targetType, object parameter,
        System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }

    #endregion
}

插入资源路径

<local:InverseBooleanConverter x:Key="InverseBooleanConverter"/>

原文描述上存在相关的资源路径报错的问题,参考其他案例,可以在grid控件内加上资源,未出现资源文件未找到而报错的问题
代码如下:

  <Grid.Resources>
            <local:InverseBooleanConverter x:Key="InverseBooleanConverter"/>
        </Grid.Resources>

值转化相关的案例

<TextBox HorizontalContentAlignment="Center"
         Text="{Binding StepDistanceZ}" 
         IsEnabled="{Binding IsChecked,ElementName=rBtnContinue,Converter={StaticResource InverseBooleanConverter}}"/>
<RadioButton x:Name="rBtnContinue" Content="连续" IsChecked="True"/>
