    if (Model.MembershipProgram.StsSignUpCountry)
    {
        <div class="form-group col-12">
           @Html.DropDownListFor(m => m.country, 
          new SelectList(Model.CountryLists, "CountryCode", "CountryName"),
          "Select Country",
            new
            {
                id = "select_country",
                @class = "form-control"
            })
        </div>
    }

<button type="submit" id="register-submit-btn" class="btn btn-primary pull-right active" name="command" value="Save">
            @ViewBag.JoinNow <i class="m-icon-swapright m-icon-white"></i>
</button>
}

yes i was removed that, but the warning keep showing :\. before i dont use that — MAS, Nov 01 '19 at 06:45
I think the problem is some how it is adding `data-val="true"` which is causing this issue. You need to check some where in your model from which you are binding it is written. — शेखर, Nov 01 '19 at 08:05
are you using the same name "country" in your code some where can you show more code like which model you are using on your cshtml file. — शेखर, Nov 01 '19 at 12:55

Just make value= false in web.config for ClientValidationEnabled

<appSettings><add key="ClientValidationEnabled" value="false" /></appSettings>

might be duplicat of : ASP .NET MVC Disable Client Side Validation at Per-Field Level

may be it helps: If your are using MVC4 and latest version you can write it as

 @{ Html.EnableClientValidation(false); }
 if (Model.MembershipProgram.StsSignUpCountry)
 {
    <div class="form-group col-12">
       @Html.DropDownListFor(m => m.country, 
      new SelectList(Model.CountryLists, "CountryCode", "CountryName"),
      "Select Country",
        new
        {
            id = "select_country",
            @class = "form-control"
        })
    </div>
}
@{ Html.EnableClientValidation(true); }

ddn't work :' the message still showing, that make me cant submit the form – MAS Nov 01 '19 at 07:04
did you write @Html.ValidationMessage for country? or it is giving system generated message. if you have written it you should remove that. – Ravi Mali Nov 01 '19 at 07:33
try this @Html.DropDownListFor(m => m.country, new SelectList(Model.CountryLists, "CountryCode", "CountryName"), "Select Country", new { id = "select_country", data_val = "false", @class = "form-control" }) – Ravi Mali Nov 01 '19 at 07:44

Problem could be CountryCode.
Check your model if it is an integer then it should be like

 public int? CountryCode{ get; set; }

You will have a model with two properties at least

  public int CountryCode{ get; set; }
  public string CountryName{ get; set; }

You have mentioned in your code as below

new SelectList(Model.CountryLists, "CountryCode", "CountryName"),
