关于WPF实现方向绑定选中的要求
[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"/>
