在我的Silverlight应用程序中,我在该页面内有主页面,我有6个按钮(Page1,page2,Back,Forward,en-US,ja-JP)。
在MainPage框架中加载第1页的TextBox与属性捆绑在一起然后我加载第2页并将语言更改为Ja-Jp并单击Page1的选定后退按钮,但是在第1页文本框中未更改的语言是该代码。请帮助我来解决这个问题
TextBox Text="{Binding ElementName=page1,Path=MyLanguage.IetfLanguageTag, Mode=TwoWay}"
public XmlLanguage MyLanguage
{
get { return (XmlLanguage)GetValue(MyLanguageProperty); }
set { SetValue(MyLanguageProperty, value); }
}
public static readonly DependencyProperty MyLanguageProperty =
DependencyProperty.Register("MyLanguage", typeof(XmlLanguage), typeof(Page1), new PropertyMetadata(null, change));
private static void change(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var update = d as Page1;
update.languageChangeText.Text = ((System.Windows.Markup.XmlLanguage)(e.NewValue)).IetfLanguageTag.ToString();
}
public Page1()
{
InitializeComponent();
Binding binding = new Binding();
binding.Mode = BindingMode.TwoWay;
binding.Source = this;
//binding.RelativeSource = new RelativeSource() { Mode = RelativeSourceMode.FindAncestor, AncestorType = typeof(ContentControl), AncestorLevel = 1 };
binding.Path = new PropertyPath("Language");
binding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
this.SetBinding(Page2.MyLanguageProperty, binding);
}

看起来一切都是正确的,除了你的绑定路径
binding.Path = new PropertyPath(“Language”); 应为
binding.Path = new PropertyPath("MyLanguage");
