devexpress gridview 数据源绑定

当前所知有两种方式

当前程序使用第一种,但数据源数据增加时需要更新gridview.freshdata();

第二种方式似乎不用,以前用过,懒得测试了

方式一

1:初始化一个数据源集合对象 

   List<Student> studentl= new List<Student>();

2:绑定数据源

 gridControl1.DataSource = studentl;

3:给studentl 赋值后更新gridview

Student student =new Student{ name="xiaoli"};

studentl.Add(student);
//gridControl1.Refresh();
gridView1.RefreshData(); //不刷新不更新显示

方式二

直接datatable  dt 

dt 赋值给数据源即可.

  数据源与控件中间BindingSource 

 BindingList<FormItem> itemsBindingList = new BindingList<FormItem>();
        List<FormItem> itemsList = new List<FormItem>();
        BindingSource bs = new BindingSource();
        private void simpleButton1_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < 10; i++)
            {
                FormItem fi = new FormItem();
                fi.ItemKey = i.ToString();
                fi.Name = Guid.NewGuid().ToString();
                if (i % 2 == 0)
                {
                    fi.Enable = true;
                }
                else
                {
                    fi.Enable = false;
                }
                itemsBindingList.Add(fi);
                itemsList.Add(fi);
                bs.Add(fi);
            }          
            //this.gridControl1.DataSource = itemsBindingList;
            //this.gridControl1.DataSource = itemsList;
            this.gridControl1.DataSource = bs;
   
        }
