DataGrid的数据更新不同步问题(VS2010)

WPF的DataGrid是自动刷新的,哪个Cell的值有变化就会刷新这个是绑定完成的,不过有个前提条件就是,当你改变绑定数据源的数值的时候,必须要让你的UI知道这个数据发生变化了,比如如果你的属性完成了INotifyPropertyChanged接口,这样无论你DataGrid发生变化,还是属性发生变化,你的UI和你后台的数据是时刻同步的,同时 属性变化的时候DataGrid也会自动刷新。

View Code
public class Export : INotifyPropertyChanged
{
public decimal _GoodsAPrice;
public int GoodsCode { get; set; }
public string GoodsName { get; set; }
public string GoodsSpec { get; set; }
public string GoodsUnit { get; set; }
public OrderStatus StoreName { get; set; }
public decimal GoodsNum { get; set; }
public decimal GoodsPrice { get; set; }
public decimal GoodsAPrice
{
get { return _GoodsAPrice; }
set
{
if (value != this._GoodsAPrice)
{
this._GoodsAPrice = value;
NotifyPropertyChanged(
"GoodsAPrice");
}
}
}
public string remark { get; set; }

public event PropertyChangedEventHandler PropertyChanged;

private void NotifyPropertyChanged(String info)
{
if (PropertyChanged != null)
{
PropertyChanged(
this, new PropertyChangedEventArgs(info));
}
}


}
