小编use*_*229的帖子

我正在尝试转换一些单位.转换函数如何使用以下内容.得到以下XAML.标记在我的ViewModel中设置为唯一对象.

<TextBox Grid.Row="2" Grid.Column="0" Margin="5" HorizontalAlignment="Right" Tag ="{Binding MyObject1}" Style ="{StaticResource TextBoxStyle}"/>
<TextBox Grid.Row="2" Grid.Column="1" Margin="5" HorizontalAlignment="Right" Tag ="{Binding  MyObject2}" Style ="{StaticResource TextBoxStyle}"/>

这种风格......

        <Style x:Key="TextBoxStyle" TargetType="{x:Type TextBox}">
            <Setter Property="Text">
                <Setter.Value>
                    <MultiBinding Converter="{StaticResource EditUnitsConverterEx}">
                        <Binding RelativeSource="{RelativeSource Self}" Path="Tag"/>
                        <Binding Path="IsMetric"/>
                    </MultiBinding>
                </Setter.Value>
            </Setter>
        </Style>

用这个转换器......

class EditUnitsConverter : IMultiValueConverter
{
    MyObject item; // 
    bool IsMetric; // bool telling me what units the system is in

    public object Convert(object[] values,
                    Type targetType,
                    object parameter,
                    System.Globalization.CultureInfo culture)
    {
        string sResult = ""; …
