Sorting data within date range

Question

Hello Team,

In my window application, am using dataGridview table and dateTimepicker to sort data in date range even though it is working but if I tried sorting only 2023 year data it end up as well sorting 2022 year data.

 public void SortBaptismalCandidate()
        {
            int i = 0;
            dataGridView3.Rows.Clear();
            cn.Open();
            cm = new SqlCommand("Select * from tblBaptismal where SDate between'" + BaptismalDt1.Value.ToString("dd-MM-yyyy") + "'and'" + BaptismalDt2.Value.ToString("dd-MM-yyyy") + "%'", cn);
            dr = cm.ExecuteReader();
            while (dr.Read())
            {
                i++;
                dataGridView3.Rows.Add(i, dr["id"].ToString(), dr["SDate"].ToString(), dr["bFName"].ToString(), dr["bLName"].ToString(), dr["bGender"].ToString(), dr["bDOB"].ToString(), dr["bPhoneNo"].ToString(), dr["bLocation"].ToString(), dr["bFatherName"].ToString(), dr["bMotherName"].ToString(), dr["bPhoneNumber"].ToString());
            }
            dr.Close();
            cn.Close();
        }
