How to Properly Group Radio Buttons in ASP.NET MVC 5 Forms?

Group Radio Buttons in ASP.NET MVC 5

When creating a form with multiple questions that require radio buttons as input options, it's necessary to group them appropriately to ensure correct functionality. The challenge faced in the provided code was that all radio buttons were falling into a single group, causing the deselection of previous answers when a new one was chosen.

Resolving the Issue

The key to resolving this issue lies in generating unique names for each group of radio buttons. This can be achieved by incorporating the associated question's identifier into the name attribute of each radio button. To achieve this, modify the code as follows:

@foreach (var question in Model.GeneralQuestions)
{
    <div class = "well">
        <h3>
            <strong>@question.QuestionString</strong>
        </h3>
        @foreach (var answer in question.PossibleAnswers)
        {
            @Html.RadioButtonFor(model => question.QuestionString + "_" + answer.Answer, answer.Answer)
            @Html.Label(answer.Answer)
            <br />
        }
    </div>
}

By adding "_question_string_" as a prefix to the answer name for each question, the radio buttons will be grouped accordingly. This will allow the correct answer to be submitted for each question without conflicts.
