                aRequestHTML = objWebClient.DownloadData(url);
        UTF8Encoding utf8 = new UTF8Encoding();
        string myString = null;
        myString = utf8.GetString(aRequestHTML);

        Regex r = new Regex("

        MatchCollection mcl = r.Matches(myString);


        ArrayList aray = new ArrayList();

        foreach (Match ml in mcl)
        {

            foreach (Group g in ml.Groups)
            {
                string bminor = g.Value;
                bminor = string.Format("{0}", g.Value);
                aray.Add(bminor);

            }
        }

        WebClient objWebClient2 = new WebClient();
        string bminor2 = myString;
        byte[] aaRequestHTML;
        aaRequestHTML = objWebClient2.DownloadData(bminor2);

        string myString2 = null;
        myString2 = utf8.GetString(aaRequestHTML);

        Regex d = new Regex("");
        MatchCollection mcl3 = d.Matches(myString2);

        ArrayList aray2 = new ArrayList();

        foreach (Match ml3 in mcl3)
        {

            foreach (Group descrip in ml3.Groups)
            {
                string des = descrip.Value;
                des = string.Format("{0}", descrip.Value);
                aray2.Add(des);

            }
        }

        DataTable dt = new DataTable();
        DataRow dr = null;
        dt.Columns.Add(new DataColumn("Column1", typeof(string)));
        for (int i = 0; i < aray.Count; i++)
        {
            dr = dt.NewRow();
            dr["Column1"] = aray[i].ToString();
            dt.Rows.Add(dr);
        }

        dt.Columns.Add(new DataColumn("Column2", typeof(string)));
        for (int i = 0; i < aray2.Count; i++)
        {
            dr = dt.NewRow();
            dr["Column2"] = aray2[i].ToString();
            dt.Rows.Add(dr);
        }


        DataGrid1.DataSource = dt;
        DataGrid1.DataBind();
