        public void UpdateNomineeByID()

        {

            UHRMS_Nominee objNominee = new UHRMS_Nominee();

            objNominee.Employee_ID = int.Parse(Request.QueryString["EmployeeID"]);

            objNominee.Emp_Nominee_ID = int.Parse(hdnNomineeID.Value);

            objNominee.Relationship = TxtRelationship.Text;

            objNominee.Nominee_Name = TxtName.Text;

            //**************************************************************************//

            string Dob = TxtDob.Text;

            DateTimeFormatInfo dateTodateInfo = new DateTimeFormatInfo();

            dateTodateInfo.ShortDatePattern = "dd/MM/yyyy";

            DateTime validDObDate = Convert.ToDateTime(Dob, dateTodateInfo);

            //**************************************************************************//

            objNominee.Date_of_Birth = validDObDate;

            TextBox txtAddress = (TextBox)NomineeAddress.FindControl("txtAddress");

            objNominee.Address = txtAddress.Text;

            DropDownList ddlCity = (DropDownList)NomineeAddress.FindControl("ddlCity");

            objNominee.City_ID = int.Parse(ddlCity.SelectedItem.Value);

            TextBox txtZip = (TextBox)NomineeAddress.FindControl("txtZipCode");

            objNominee.Zip_code = txtZip.Text;

            TextBox txtPhone = (TextBox)NomineeAddress.FindControl("txtPhoneNo");

            objNominee.Phone_No = txtPhone.Text;

            TextBox txtMob = (TextBox)NomineeAddress.FindControl("txtFaxNo");

            objNominee.Mobile_No = txtMob.Text;

           

            objNominee.Email_ID = TxtEmailID.Text;

            objNominee.Modified_On = DateTime.Now;

            objNominee.ModifiedBy = 1;

            objNominee.Is_Active = true;

            objNominee.Is_Deleted = false;

            //**************************************************************************//

            if (FileUpload1.HasFile == false)

            {

             //Bind your image url in a hidden field hdnPhotoURL.Value="Image Url From Your Database";

                string[] photo = hdnPhotoURL.Value.Split(new char[] { '.' });

                int i = photo.Length;

                string extension = photo[i - 1];

 //if you do not want to change the name of that photo url you just take another hiddenfield and store the previous Employee Name and pass the value like TxtName.Text="Your previous name from database" ;

                string NewPhoto = Request.QueryString["Employee_ID"] + TxtName.Text + "." + extension;

                objNominee.Photo = NewPhoto;

              

            }

            else

            {

                //********** To rename the uploaded photo ************//

                string[] photo = FileUpload1.FileName.Split(new char[] { '.' });

                int i = photo.Length;

                string extension = photo[i - 1];

                string NewPhoto = Request.QueryString["Employee_ID"] + TxtName.Text + "." + extension;

                objNominee.Photo = NewPhoto;

                string newFile = "";

                for (int j = 0; j < i - 2; i++)

                {

                    newFile += photo[j];

                }

                //**********************************************************//

                FileUpload1.SaveAs(Server.MapPath("~/images/ERP/HRMS/Nominee/" + NewPhoto));

            }

            ERPManagement.GetInstance.UpdateNomineeByID(objNominee);

        }
