code is here:

        con.Open();
        da = new SqlDataAdapter(str, con);
        da.Fill(ds);
        PlaceHolder1.Controls.Clear();
        Table tbl = new Table();
        PlaceHolder1.Controls.Add(tbl);

        for ( i = 0; i < 5; i++)
        {
            TableRow tr = new TableRow();
            for (int j = 0; j < 2; j++)
            {
                TableCell tc = new TableCell();
                HyperLink h1 = new HyperLink();
                Image img = new Image();
                ImageButton imgbt = new ImageButton();
                if (j == 0)
                {
                    imgbt.ImageUrl = ds.Tables[0].Rows[i]["picture"].ToString();
                    imgbt.Height = 50;
                    imgbt.Width = 50;
                      imgbt.Click += new ImageClickEventHandler(imgbt_Click);

                   ds.Tables[0].Rows[i]["picture"].ToString();

                   tc.Controls.Add(imgbt);
                }
                else

                    h1.Text = ds.Tables[0].Rows[i]["Name"].ToString();
                    // Add the control to the TableCell
                    tc.Controls.Add(h1);

            tbl.Rows.Add(tr);
        }
    }
    catch { }
