Binding Or Populating Radio Button List in Asp.Net MVC Using Model

8/16/2017 - By Pranav Singh 0

This article will show you how you can binding radiobuttonlist or radiobutton in asp.net mvc using model  or Radiobuttonlist in MVC 5 using Model, Radiobuttonlistfor values.

So for this article first we will create a new asp.net mvc application add a model class file in it. After that we will add the below code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MVC_Demos.Models
{
    public class RadioButtonLiatModel
    {
        public List<RadioButtonData> RadioButtonListData { get; set; }
    }
    public class RadioButtonData
    {
        public int Id { get; set; }
        public string Value { get; set; }
    }
}

After this we will add a controller class file and add the below code into the controller class file.

public class RadioButtonListController : Controller
    {
        //
        // GET: /RadioButtonList/

        public ActionResult Index()
        {
            RadioButtonLiatModel _radiobuttonliatmodel = new RadioButtonLiatModel();
            _radiobuttonliatmodel.RadioButtonListData = new List<RadioButtonData>();
            _radiobuttonliatmodel.RadioButtonListData.Add(new RadioButtonData { Id = 1, Value = "Item 1" });
            _radiobuttonliatmodel.RadioButtonListData.Add(new RadioButtonData { Id = 2, Value = "Item 2" });
            _radiobuttonliatmodel.RadioButtonListData.Add(new RadioButtonData { Id = 3, Value = "Item 3" });
            _radiobuttonliatmodel.RadioButtonListData.Add(new RadioButtonData { Id = 4, Value = "Item 4" });
            return View(_radiobuttonliatmodel);
        }
    }

In above code I have created a list of data with model and return into the view. After this we will create the view and add the below code.

@model MVC_Demos.Models.RadioButtonLiatModel
@{
    ViewBag.Title = "Binding Radio Button List in Asp.Net MVC Using Model";
    <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
}
<h2>RadioButton List</h2>
<br />
@foreach (var item in Model.RadioButtonListData)
{
    <input type="radio" id="@item.Id" value="@item.Id" name="radiobutton" />@item.Value
}

Here in above code you need to take care of one thing. Just check the highlighted part of the code this is containing the name of the control. This should be common for all the radio button, because if we don’t have common radio button name then we will not be able to select the single radio button as per it’s nature.

Now we have done run the application and check the output.
