            if (dsDesignation != null && dsDesignation.Tables[0].Rows.Count > 0)
            {
                foreach (DataRow dr in dsDesignation.Tables[0].Rows)
                {
                    dnDesignatin.Add(Convert.ToString(dr["DesignationName"]), Convert.ToString(dr["TargetScore"]));
                }
