Answer 2

在wpf里要学会用绑定和通知        <ListView x:Name="dgv_SellList">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="CD" DisplayMemberBinding="{Binding curGoodsCD}"></GridViewColumn>
                    <GridViewColumn Header="Name" DisplayMemberBinding="{Binding curGoodsName}"></GridViewColumn>
                    <GridViewColumn Header="Count" DisplayMemberBinding="{Binding curGoodsCount}"></GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>
            //定义person类
        class Person:INotifyPropertyChanged
        {
            public event PropertyChangedEventHandler PropertyChanged;
            private string _curGoodsCD;
            public string curGoodsCD 
            {
                get { return _curGoodsCD; }
                set
                {
                    _curGoodsCD = value;
                    if (PropertyChanged != null)
                    {
                        PropertyChanged(this, new PropertyChangedEventArgs("curGoodsCD"));
                    }
                }
            }
            private string _curGoodsName;
            public string curGoodsName
            {
                get { return _curGoodsName; }
                set
                {
                    _curGoodsName = value;
                    if (PropertyChanged != null)
                    {
                        PropertyChanged(this, new PropertyChangedEventArgs("curGoodsName"));
                    }
                }
            }
            private string _curGoodsCount;
            public string curGoodsCount
            {
                get { return _curGoodsCount; }
                set
                {
                    _curGoodsCount = value;
                    if (PropertyChanged != null)
                    {
                        PropertyChanged(this, new PropertyChangedEventArgs("curGoodsCount"));
                    }
                }
            }
        }            //在构造函数里进行数据绑定
            Person p = new Person { curGoodsCD = "A", curGoodsName = "C", curGoodsCount = "C"};
            List<Person> s = new List<Person>() { 
            new Person { curGoodsCD = "A", curGoodsName = "C", curGoodsCount = "C"}
            };
            dgv_SellList.ItemsSource = s;            //按钮单击事件里写
            Person per = dgv_SellList.Items[0] as Person;
            per.curGoodsName = "AA";
