DataTable dt = new DataTable();
            try
            {
                Con_Open();
                cmd = new SqlCommand("select * from Stu", con);
                dr = cmd.ExecuteReader();
                if (dr.HasRows)
                {
                    dt.Columns.Add(new DataColumn("Reg No"));
                    dt.Columns.Add(new DataColumn("Name"));
                    dt.Columns.Add(new DataColumn("Mark1"));
                    dt.Columns.Add(new DataColumn("Mark2"));
                    dt.Columns.Add(new DataColumn("Mark3"));
                    while (dr.Read())
                    {
                        DataRow temp;
                        temp = dt.NewRow();
                        temp[0] = (System.Convert.IsDBNull(dr[0]) ? "" : dr[0].ToString());
                        temp[1] = (System.Convert.IsDBNull(dr[1]) ? "" : dr[1].ToString());
                        temp[2] = (System.Convert.IsDBNull(dr[2]) ? "" : dr[2].ToString());
                        temp[3] = (System.Convert.IsDBNull(dr[3]) ? "" : dr[3].ToString());
                        temp[4] = (System.Convert.IsDBNull(dr[4]) ? "" : dr[4].ToString());
                        dt.Rows.Add(temp);
                    }
                    cmd.Dispose();
                    dr.Close();
                    con.Close();
                }
                else
                {

                    dt.Columns.Add(new DataColumn("Records"));
                    DataRow temp;
                    temp = dt.NewRow();
                    temp[0] = "No Records Found!!";
                    dt.Rows.Add(temp);
                }
