        string password = Encrypt(pwd);
        string re_password = Encrypt(re_pwd);
        login_name =  txt_username.Text.ToLower();
      
        try
        {

           
                if (password == re_password)
                {
                    con.Close();
                    cmd = new SqlCommand("select id from login_detail where loginname='" + txt_pname.Text + "'", con);
                    con.Open();
                    SqlDataReader rd = cmd.ExecuteReader();
                    rd.Read();
                    if (!rd.HasRows)
                    {
                        con.Close();

                        cmd = new SqlCommand("select value from main_master where description='patient'", con);
                        con.Open();
                        string roleid = cmd.ExecuteScalar().ToString();
                        con.Close();
                        cmd = new SqlCommand("proc_patient_detail", con);
                        cmd.CommandType = CommandType.StoredProcedure;
                        cmd.Parameters.AddWithValue("@login_name", login_name);
                        cmd.Parameters.AddWithValue("@password", password);
                        cmd.Parameters.AddWithValue("@roleid", roleid);
                        cmd.Parameters.AddWithValue("@user_sts", 1);
                        cmd.Parameters.AddWithValue("@login_sts", 0);
                        cmd.Parameters.AddWithValue("@patient_name", txt_pname.Text);
                        cmd.Parameters.AddWithValue("@address", txt_paddress.Text);
                        cmd.Parameters.AddWithValue("@mobile_no", txt_pmobile.Text);
                        cmd.Parameters.AddWithValue("@emailid", txt_pemail.Text);
                        cmd.Parameters.AddWithValue("@streamid", login_name);
                        cmd.Parameters.AddWithValue("@amount", txt_amount.Text);

                        con.Close();
                        con.Open();
                        cmd.ExecuteNonQuery();
                        con.Close();
                        sendmail();
                        ClientScript.RegisterClientScriptBlock(this.GetType(), "success", "alert('Submitted Successfully');window.location.href='editpatient.aspx';", true);

                        //Response.Redirect("addpatient.aspx");
                    }
                    else
                    {
                        lbl_loginmsg.Text = "User Already Exist";
                        lbl_loginmsg.Visible = true;
