Example of Model Binding
Here, we will create a simple model binding with controller and View. Here we are creating a Student model with some properties, and we will use those properties to create form fields.
Create a Model
To create a Model, right-click on the Model folder and add class. Now edit the default code with the below-given code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MvcApplicationDemo.Models
{
public class Student
{
public int ID { get; set; }
public string Name { get; set; }
public string Contact { get; set; }
public string Email { get; set; }
}
}
Create a Controller
After creating the model, we will now create a controller by Right-clicking on the controller folder and adding the class as shown below:
Now add the following code in it:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MvcApplicationDemo.Controllers
{
public class StudentsController : Controller
{
// GET: Students
public ActionResult Index()
{
return View();
}
}
}
Creating a view
To create View, right-click on the index action method, and by selecting add view option, add the View and the corresponding model to the file.
The default file will contain some predefined code change that code with the following code:
@model MvcApplicationDemo.Models.Student
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Student</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Contact, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Contact, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Contact, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
Output
Upon executing, the index file produces the following output:
