C#/.NET Winform绑定数据源后数据变化界面参数也改变

C#/.NET Winform绑定数据源后数据变化界面参数也改变

1、添加引用using System.ComponentModel;

2、数据源的实体类Model继承自：INotifyPropertyChanged

3、显式实现接口委托public event PropertyChangedEventHandler PropertyChanged = delegate { };

4、在数据改变时需要通知窗体的属性加上PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("xxx"));

5、调用实例

该实例只有Selected变化时窗体会跟随变化，其他属性不会

    public class BindingModel: INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged = delegate { };

        private bool _selectd;
        /// <summary>
        /// 是否选中
        /// </summary>
        public bool Selected {
            get => _selectd;
            set
            {
                _selectd = value;
                PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Selected"));
            }
        }

        /// <summary>
        /// 序号
        /// </summary>
        public int RowIndex { get; set; }

        /// <summary>
        /// 商品ID
        /// </summary>
        public string ItemId { get; set; }

        /// <summary>
        /// 标题
        /// </summary>
        public string Title { get; set; }

        /// <summary>
        /// 访客数量
        /// </summary>
        public int VisitorNumber { get; set; }

        /// <summary>
        /// 浏览量
        /// </summary>
        public int PageViewsNumber { get; set; }
