textbox and dropdown is not accepting the value in mvc

thank you
if I add model.isvalid ,it always return false.

If not, please provide more relevant part code to check with (hard to understand from current block).

hi sir,


i have form with field first name,last name,email,phone and gender etc
Here phone is a text box which accept integer value.my problem is in this text box. It is not accepting the given phone number value instead it is inserting only null value.but other values are varchar value,it got inserted. i am using sql 2016 database

this is the cshtml of phoneno


 <tr>
                <td>
                    @Html.LabelFor(a=>a.Phoneno)
                </td>
            </tr>
            <tr>
                <td>
                    @Html.TextBoxFor(a=>a.Phoneno)

                </td>

            </tr>

i have created separate class library project.this class library project as edmx .model value of phoneno is coming from this edmx.
model cs of edmx

public int Phoneno { get; set; }

controller cs for passing values

 mydbs itr = new mydbs(); -this is class library project
                string result = itr.insertcmd(reg); -this is the method in that class file
                ViewData["result"] = result;


code in class library


 public string insertcmd(registration reg)
        {
           using (customerEntities con = new customerEntities())
            {

                string result = con.registrations.Add(reg).ToString();
                con.SaveChanges();
                return result;




            }

        }

    }
