TextBlock绑定不起作用,我不知道为什么……
(此代码有效,但TextBlock未更新) XAML <TextBlock x:Name="filterAllText" Text="{Binding UpdateSourceTrigger=PropertyChanged}" /> 代码隐藏 filterAllText.DataContext = LogSession.test.MyCoynt; C# public class Test : INotifyPropertyChanged { public int myCoynt; public int MyCoynt { get { return myCoynt; } set { myCoynt = value; NotifyPropertyChanged(); } } public event PropertyChangedEventHandler PropertyChanged; protected virtual void NotifyPropertyChanged( [CallerMemberName] String propertyName = "") { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) { handler(this,new PropertyChangedEventArgs(propertyName)); } } 解决方法
