    public int AddPatient(Patient obj)
    {
        using (var con = new SqlConnection(str))
        {
            using (var com = new SqlCommand("AddPatient", con))
            {
                com.CommandType = CommandType.StoredProcedure;
                com.Parameters.AddWithValue("@Name", obj.Name);
                com.Parameters.AddWithValue("@Address", obj.Address);
                com.Parameters.AddWithValue("@DateOfBirth", obj.DateOfBirth);

        string name = TxtName.Text;
        string address = TxtAddress.Text;
        DateTime dateofbirth =Convert.ToDateTime(TxtDateOfBirth.Text);
        int phone = Convert.ToInt32(TxtPhone.Text);
        int emergencyno=Convert.ToInt32(TxtContact.Text);
        DateTime registrationdate =Convert.ToDateTime(TxtRegistrationDate.Text);
        PatientBusiness PB = new PatientBusiness();
        Patient obj = new Patient();
        try
        {
            obj.Name = name;
            obj.Address = address;
            obj.DateOfBirth = dateofbirth;
            obj.Phone = phone;
            obj.EmergencyContact = emergencyno;
            obj.DateOfRegistration = registrationdate;
            PB.Add(obj);
            LblMessage.Text = "Patient has been added successfully";
            TxtName.Text = "";
            TxtAddress.Text = "";
            TxtDateOfBirth.Text = "";

        }

        {
            PB = null;
        }

I don't understand your question but after reviewing your code, I can only recommand you to consider using an ObjectDataSource combined with a FormView and stop doing "business stuff" in code behind.
