c# INotifyPropertyChanged實作

網路上已經有許多INotifyPropertyChanged的文章
看了許多但還是不太懂所以看著msdn實作了一次
1.先新增一個class

        public int id { get; set; }
        public string name { get; set; }

2.將class繼承INotifyPropertyChanged

        using System.ComponentModel;
        public class member : INotifyPropertyChanged

3.實作INotifyPropertyChanged

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

4.修改class

  public int id { get; set; }

        private string _name;
        public string name
        {
            get { return this._name; }
            set
            {
                if (value != this._name)
                {
                    this._name = value;
                    NotifyPropertyChanged("Name");
                }
            }
        }

5.新增一個list(抓假資料如果是資料庫也可直接改)

  public List GetMember(int pCount)
        {
            List lst = new List();
            string name = "test";
            for (int i = 0; i < pCount; i++)
            {
                member create = new member()
                {
                    id = i,
                    name = name + i.ToString()
                };
                lst.Add(create);
            }
            return lst;
        }

6.抓出資料

 member script = new member();
 List lst = script.GetMember(10);
 dataGridView1.DataSource = lst;

7.寫另一個頁面去修改name
會發覺改了後dataGridview1的name也會跟著改
太神奇又好用了

Html5 Form內按Enter無效

有時用jQuery或其他方式自訂了Enter的function後會不需要form的submit

<form action="xxx.php" method="post"  onsubmit="return false;">
</form>
