Perform Operations on WebForms From MVC

Note: Please build the solution before scaffolding.

Step 8: Create a Empty MVC 5 Controller.

This will add the Content, App_Start, fonts and Views folders to the project automatically. Now modify your controller with the code below:

using Newtonsoft.Json;
using System.Web.Mvc;
using WebFormsToMvcApp.Models;
namespace WebFormsToMvcApp.Controllers
{
    public class CricketerController : Controller
    {
        //
        // GET: /Cricketer/
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult Edit()
        {
            string Jason_Data = Request.Form["FormToMVC"];
            Cricketer CricObj = JsonConvert.DeserializeObject<Cricketer>(Jason_Data);
            return View(CricObj);
        }
        public void Update(Cricketer CricObj)
        {
            CricketerSite_Entities CricDb = new CricketerSite_Entities();
            Cricketer Cric_Exist = CricDb.Cricketers.Find(CricObj.ID);
            Cric_Exist.Name = CricObj.Name;
            Cric_Exist.Team = CricObj.Team;
            Cric_Exist.Grade = CricObj.Grade;
            CricDb.SaveChanges();
            Response.Redirect("/DataWebForm.aspx?cricketerid=" + CricObj.ID);
        }
    }
}

In the code above, the Edit action method is used to read the JSON data sent from the webform and then the JSON.NET library is used to desterilize the JSON string ("FormToMVC") into the Cricketer class object.

We have also created the Update() to get the information of the Edit() View. It receives the data as the Cricketer object. It simply applies the changes to the database.

Step 9: Modify the Global.asax file with the following code:

using System;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
namespace WebFormsToMvcApp
{
    public class Global : System.Web.HttpApplication
    {
        protected void Application_Start(object sender, EventArgs e)
        {
            AreaRegistration.RegisterAllAreas();
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
    }
}

Creating View

In this section we'll create the view for the controller using the following procedure.

Step 1: Right-click on the Edit method for adding the view.

Step 2: Edit and modify the view with the following code:

@model WebFormsToMvcApp.Models.Cricketer
@{
    ViewBag.Title = "Edit Cricketer";
}
<h2>Edit</h2>
@using (Html.BeginForm("Update","Cricketer",FormMethod.Post))
{
    <div class="form-horizontal">
        <h4>Cricketer</h4>
        <hr/>
        <div class="form-group">
            @Html.LabelFor(model=> model.ID)
            <div class="col-md-10">
                @Html.TextBoxFor(model=> model.ID)
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Name)
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.Name)
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Team)
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.Team)
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Grade)
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.Grade)
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-10">
                <input type="submit" value="Update" />
            </div>
        </div>
    </div>
}

The code defined above submits the data to the Update method.

Step 3: Now at last add the following code to the DataWebForm's Page_Load() event:

public partial class DataWebForm : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!string.IsNullOrEmpty(Request.QueryString["cricketerid"]))
        {
            Literal1.Text = "Cricketer" + Request.QueryString["cricketerid"] + "Updated Successfully";
        }
    }
}

That's it. You can see the following figure of Solution Explorer to view the entire project:

Running the Application

Step 1: Run the DataWebForm and click on the Edit button to update the data

Step 2: Update the info and click on the Update

In the next screenshot you can see that the data was updated successfully.
