gridview数据绑定

Gridview的绑定方式之一：

 DataView dt = new DataView();   //新建一个DataView对象，可作为DataSource
            DataTable dtt = new DataTable("haha");
            {
                dtt.Columns.Add("a");
            }
            DataRow dr = dtt.NewRow();
            dr[0] = "a";
            dtt.Rows.Add(dr);
            dt.Table = dtt;
            this.GridView1.DataSource = dt;
            this.GridView1.DataBind();
