通知屬性更改不工作

Question

這是我的XML代碼

<TextBlock Grid.Column="0" Tag="{Binding id,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" Text="{Binding Name,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"/> 

這是我的模型

public string _Name; 
public string Name 
{ 
    get { return _Name; } 
    set { _Name = value; RaisePropertyChanged("Name"); } 
}  

當我設置值這兩個propertie即。以標識和名稱

，但它不是對通知名稱...

簡單數據綁定實例與更新。您可以使用此作爲參考，讓你開始:)

public partial class MainWindow : Window, INotifyPropertyChanged 
{ 
    // implement the INotify 
    public event PropertyChangedEventHandler PropertyChanged; 
    private void NotifyPropertyChanged(String propertyName) 
    { 
     PropertyChangedEventHandler handler = PropertyChanged; 
     if (null != handler) 
     { 
      handler(this, new PropertyChangedEventArgs(propertyName)); 
     } 
    } 

    private string _mytext; 
    public String MyText 
    { 
     get { return _mytext; } 
     set { _mytext = value; NotifyPropertyChanged("MyText"); } 
    } 

    public MainWindow() 
    { 
     InitializeComponent(); 
    } 

    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     this.DataContext = this;    // set the datacontext to itself :) 
     MyText = "Change Me"; 
    } 
}
