This example demonstrates how to implement the INotifyPropertyChanged interface and use PropertyChangedEventHandler. For the complete code listing, see the XAML data binding sample.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DataBinding
{
public class Employee : INotifyPropertyChanged
{
private string _name;
private string _organization;
public string Name
{
get { return _name; }
set
{
_name = value;
RaisePropertyChanged("Name");
}
}
public string Organization
{
get { return _organization; }
set
{
_organization = value;
RaisePropertyChanged("Organization");
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void RaisePropertyChanged(string name)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(name));
}
}
}
}
