ASP.NET MVC - How to Specify the Value in TextBox

Question

How do I specify the Value that should be entered into the Textbox. I dont want to use dropdownlist. I want to accept only these three (3) values Nigeria, Ghana and Togo

If any other value is entered it should not save or hide or disable the Save button.

View

<div class="col-md-12">
    <div>
        @Html.LabelFor(model => model.COUNTRY_NAME, "Country Name")                               
        @Html.TextBoxFor(model => model.COUNTRY_NAME, new { @style = "border-radius:3px;", @type = "text", @class = "form-control", @placeholder = "Country Name", @autocomplete = "on" })
        @Html.ValidationMessageFor(model => model.COUNTRY_NAME, null, new { @class = "text-danger" })
    </div>
</div>

Please how do I achieve this?

When you submit the form, you can validate textbox value with jQuery.

<button onclick="validateData();"></button>

Then write a validation method as follows.

function validateData() {
    if (Nigeria, Ghana and Togo) {
        //ajax post to your controller
    } else {
        //return error message
    }
}
