<div class="form-group col-12"> <select class="form-control" data-val="true" data-val-required="The country field is required." id="select_country" name="country"> <option value="">Select Country</option> <option value="CO0169">Yemen</option> <option value="CO0170">Zambia</option> <option value="CO0171">Zimbabwe</option> ... </select> </div> — MAS

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

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

Ravi Mali Over a year ago

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 Over a year ago

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" })

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"),
