Send parameters to ASP.Net SqlDataSource from class file using C#

I am using the code shown below to enter a record into SQL server.

I tested my code with the values that I entered manually, and it works correctly but if I get the value from person class it doesn't insert or update that parameter.

How can I do it  right?!

I have defined SqlDataSource and typed InsertParameters and UpdateParameters as shown below, 

                <asp:SqlDataSource ID="sqlDtSrcEmployees" runat="server" 
                    ConnectionString="<%$ ConnectionStrings:KDUIS-v1ConnectionString %>"
                    SelectCommand ="SELECT * FROM [IMS_Person]"
                    InsertCommand="INSERT INTO [IMS_Person] ([GuidId], [FirstName], [LastName], [FatherName], [NationalCode], [BirthDate], [CertificateNo], [BirthPlace],
                [BirthCertificatePlace], [Gender], [ReligionId], [MaritalId], [Mobile], [Email], [CreateDate], [Description])
                    VALUES (@GuidId, @FirstName, @LastName, @FatherName, @NationalCode, @BirthDate, @CertificateNo, @BirthPlace, @BirthCertificatePlace, @Gender, @ReligionId,
                @MaritalID, @Mobile, @Email, @CreateDate,@Description)"
 		UpdateCommand="Update IMS_Person SET [FirstName]=@FirstName,[LastName]=@LastName,[FatherName]=@FatherName,[NationalCode]=@NationalCode,

I get this parameter GuidId, Gender, ReligionId, MaritalID and CreateDate  from a class person that I write it before

     public int Gender(string genderlist)
        {

            switch (genderlist)
            {
                case "woman":
                    return 0;

                case "man":
                    return 1;

                default:
                    return -1;

            }

        }


     public int Religion(string religionlist)
        {
            switch (religionlist)
            {
                case "Muslim":
                    return 1;

                case "Christianity":
                    return 2;

                default:
                    return -1;

            }

        }



        public int Marital(string maritallist)
        {
            switch (maritallist)
            {
                case "Single":
                    return 1;

                case "Married":
                    return 2;
                default:
                    return -1;

            }

        }


      public Guid GenerateGuid()
        {
            Guid guidid = System.Guid.NewGuid();
            return guidid;

        }



        public string CreateDateTime()
        {
            ///////date &time of insert onfo of person
            ///// use of datetime utc
            TimeZoneInfo timeZoneInfo;

            DateTime dateTime;

            //Set the time zone information to Iran Standard Time

            timeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById("Iran Standard Time");

            //Get date and time in Iran Standard Time

            dateTime = TimeZoneInfo.ConvertTime(DateTime.UtcNow, timeZoneInfo);

            //Print out the date and time
            string datetimeinsert = dateTime.ToString();
            return datetimeinsert;
        }
