亲爱的先生， 我正在检索数据库中的数据以及存储在数据表中的数据。 ，我想将数据表数据绑定到指定单元格中的动态gridview列。 我正在尝试这样做。 我们正在开发项目3层建筑

Dear sir, I am retrieving data fro database and that data stored in datatable. and i want to bind datatable data to dynamic gridview columns in the specied cell. I am trying like this. we are developping the project 3-tier architeture

dk = tbal.retriveheaderdata(clas, sec, k1, tim1); for (int hj = 0; hj < dk.Rows.Count; hj++) { TableCell tc = new TableCell(); Label ll = new Label(); ll.ID = f + hj.ToString(); tc.Controls.Add(ll); tc.Text = dk.Rows[hj].ToString(); GridView2.Rows[hj].Cells.Add(tc); }
