namespace INotifyPropertyChanged範例
{
public class VM:INotifyPropertyChanged
{
//首先,定義PropertyChanged event
public event PropertyChangedEventHandler PropertyChanged;
//第二步,建立Method來發動事件
protected void OnPropertyChanged(string prop)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(prop));
}
public VM()
{
}
//最後,當屬性改變時,呼叫 OnPropertyChanged
private string name;
public string Name
{
get { return name; }
set
{
name = value;
//在設定 name 值後,要呼叫 OnPropertyChanged 通知 view 此屬性已變更
OnPropertyChanged("Name");
}
}
}
