WPF DataGrid的数据更新不同步问题(VS2010)

来源:互联网 时间:1970-01-01

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。

        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));
                }
            }


        }
