WPF怎样实现数据库数据更新后实现INotifyPropertyChanged-CSDN论坛

Answer 1

首先创先一个实体类
public class MyClass : INotifyPropertyChanged
{
private static string _myString = "sdfdsfssdfsdfsdfdsf";

public string MyString
{
get { return _myString; }
set
{
_myString = value;
OnPropertyChanged("MyString");
}
}

public event PropertyChangedEventHandler PropertyChanged;

[NotifyPropertyChangedInvocator]
protected virtual void OnPropertyChanged(string propertyName)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
}
}

//然后把这个实体类绑定到页面的 DataContext

<TextBox Text="{Binding MyString}"/>
