使用codeplex中的LocalizationExtension搜索变通方法以在Ribbon控件上应用本地化

    <MvvmCore:RibbonCommandExtended x:Key="SwitchLanguageCommand" 
                            CanExecute="RibbonCommandExtended_CanExecute"
                            Executed="RibbonCommandExtended_Executed"
                            LabelTitle="{lex:LocText Key=SwitchLanguage,Dict=LanRes}"
                            ToolTipTitle="{lex:LocText Key=SwitchLanguage,Dict=LanRes}"
                            LargeImageSource="{lex:LocImage Key=ChangeLanguage,Dict=LanRes}"/>

<rb:RibbonButton x:Name="EnglishButton" Command="{StaticResource SwitchToEnglishCommand}" Click="EnglishButton_Click">

这是我的RibbonCommand扩展类。

 public class RibbonCommandExtended : RibbonCommand
    {
        private ICommand m_command;
        public ICommand Command
        {
            get { return m_command; }
            set
            {
                m_command = value;
                if (m_command != null)
                {
                    this.CanExecute += UsCanExecute;
                    this.Executed += UsExecuted;
                }
                else
                {
                    this.CanExecute -= UsCanExecute;
                    this.Executed -= UsExecuted;
                }
            }
        }

        private void UsExecuted(object sender, ExecutedRoutedEventArgs e)
        {
            Command.Execute(e.Parameter);
        }

        private void UsCanExecute(object sender, CanExecuteRoutedEventArgs e)
        {
            e.CanExecute = Command.CanExecute(e.Parameter);
        }
    }

当我的程序启动时,ribbon控件会选择正确的语言字符串和图像。但是当我在运行时更改语言时,我在功能区控件本地化的文本和图像中看不到任何更改。因为RibbonCommand的LabelTitle、LargeImageSource和所有其他属性都不是依赖属性。

已经有人解决这个问题了吗?或者除了本地化扩展之外,还有其他方法可以使我的应用程序本地化,从而满足我的需求吗?
