12
13namespace WinControlLib
14{
15    public partial class UserControl3 : UserControl
16    {
17        BindingManagerBase bManager;
18        public UserControl3()
19        {
20            InitializeComponent();
21
22            
23
24            List<MapIconHistoryInfo> infos = MapIconHistoryBLL.J_M_GetHistotyNoteByMapIconID(13);
25
26            //数据源用infos ********************************************
27            //textBox1.DataBindings.Add("Text", infos, "ID");
28            //textBox2.DataBindings.Add("Text", infos, "Deadline");
29
30            //bManager = this.BindingContext[infos];
31
32            //*******************************************************
33            //数据源用 bindingSource1
34            this.bindingSource1.DataSource = infos;
35            textBox1.DataBindings.Add("Text", bindingSource1, "ID");
36            textBox2.DataBindings.Add("Text", bindingSource1, "Deadline");
37
38            bManager = this.BindingContext[bindingSource1];
39        }
40
41        private void button1_Click(object sender, EventArgs e)
42        {
43            bManager.Position -= 1;
44        }
