BusyIndi​​cator BusyContent绑定到WPF窗口中的属性不会更新

Question

我创建了一个WPF表单，其中包含来自扩展WPF工具包的BusyIndi​​cator。此窗口在新线程上运行并实现INotifyPropertyChanged。接下来，我将BusyContent绑定到在BusyContent上显示正常的属性，但似乎没有更新。有任何想法吗 ？

<StackPanel> 
    <xctk:BusyIndicator IsBusy="True" BusyContent="{Binding BusyText, Mode=TwoWay, NotifyOnSourceUpdated=True, UpdateSourceTrigger=PropertyChanged}" > 
    </xctk:BusyIndicator> 
</StackPanel> 

private string _busyText; 
    public string BusyText 
    { 
     get 
     { 
      return _busyText; 
     } 
     set 
     { 
      _busyText = value; 
      this.OnPropertyChanged("BusyText"); 
     } 
    }

我已经实现与后台线程的解决方案，它开始工作：

BackgroundWorker worker = new BackgroundWorker(); 
worker.DoWork += (o, ea) => 
    { 
     BusyText = ReceivedMessage; 
    }; 
worker.RunWorkerCompleted += (o, ea) => 
{ 
    _busyIndicator.IsBusy = false; 
}; 
_busyIndicator.IsBusy = true; 
worker.RunWorkerAsync();
