code is:

 try
        {
            string str;
 
            string username = (string)Session["username"];
            MySql.Data.MySqlClient.MySqlConnection oConn = new MySql.Data.MySqlClient.MySqlConnection(WebConfigurationManager.ConnectionStrings["filesystem"].ConnectionString);
 
            oConn.Open();
 
            MySql.Data.MySqlClient.MySqlCommand command =
                        new MySql.Data.MySqlClient.MySqlCommand("select * from usefiles where USERNAME=?user;", oConn);
 
            command.Parameters.Add(new MySql.Data.MySqlClient.MySqlParameter("?user", MySql.Data.MySqlClient.MySqlDbType.VarChar, 500));
            command.Parameters[0].Value = (string)DropDownList1.SelectedValue;
            MySqlDataReader dr = command.ExecuteReader();
 
            while (dr.Read())
            {
                string serialnumber = (string)dr["FILENAME"];
 
                System.IO.File.Delete(Server.MapPath(".") + "\\USERFOLDERS\\" + DropDownList1.SelectedValue + "\\" + serialnumber);
 
            }
            oConn.Close();
 
 
 
            //if (str.Equals("yes"))
            //{
 
            MySql.Data.MySqlClient.MySqlConnection oConn1 = new MySql.Data.MySqlClient.MySqlConnection(WebConfigurationManager.ConnectionStrings["filesystem"].ConnectionString);
 
            oConn1.Open();
 
 
            MySql.Data.MySqlClient.MySqlCommand command1 =
                new MySql.Data.MySqlClient.MySqlCommand("delete from login where USERNAME=?user;", oConn1);
            command1.Parameters.Add(new MySql.Data.MySqlClient.MySqlParameter("?user", MySql.Data.MySqlClient.MySqlDbType.VarChar, 500));
            command1.Parameters[0].Value = (string)DropDownList1.SelectedValue;
 
            command1.ExecuteNonQuery();
            oConn1.Close();
 
 
            oConn1.Open();
            MySql.Data.MySqlClient.MySqlCommand command2 =
               new MySql.Data.MySqlClient.MySqlCommand("delete from usefiles where USERNAME=?user;", oConn1);
            command2.Parameters.Add(new MySql.Data.MySqlClient.MySqlParameter("?user", MySql.Data.MySqlClient.MySqlDbType.VarChar, 500));
            command2.Parameters[0].Value = (string)DropDownList1.SelectedValue;
 
            command2.ExecuteNonQuery();
            oConn1.Close();
            System.IO.Directory.Delete(Server.MapPath(".") + "\\USERFOLDERS\\" + DropDownList1.SelectedValue);
 
            // "Delete" the row 
            //DeleteResults.Text += string.Format( "This would have deleted ProductID {0}<br />", productID);
 
            GridView1.DataBind();
 
            DropDownList1.Items.Clear();
            DropDownList1.DataBind();
           string a = "a";
            Session["status"] = a;
            Label4.Text = (string)Session["status"];
            Panel1.Visible = false;
 
        }
        catch (Exception exc)
        {
            Response.Write("<script tyep='text/javascript'>alert('Button2_Click<br/>" + exc.Message + "');</script>");
        }

Its good that you used a try catch block. Its bad that you didn't use a few. Try more debugging and report back. Thanks.
