Crud operation in single page in mvc using Json ~ Dotnet in simpleway

Today we discuss about the crud operation in single page in mvc 4

First we create model using linq to entity (using edmx file).

List of Users

User Creation

User Deletion

User Modification

User Details

Code for Controller:-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using mvcwithjson.Models;

namespace mvcwithjson.Controllers

{

public class popupmodelController : Controller

{

dbMVCEntities en = new dbMVCEntities();

public ActionResult Index()

{

return View(en.student_info.ToList ());

}

public JsonResult display(string id)

{

int srno = Convert.ToInt32(id);

var v = en.student_info.Where(m => m.id == srno).Select(m => new { ID = m.id, Name = m.name, age = m.age }).FirstOrDefault();

return Json(v, JsonRequestBehavior.AllowGet);

}

[HttpPost]

public string delete(string ID)

{

int id = int.Parse(ID);

var v = en.student_info.FirstOrDefault(m => m.id == id);

if (v != null)

{

en.student_info.Remove(v);

en.SaveChanges();

}

return "Record deleted successfully";

}

[HttpPost]

public string create( string name, int age)

{

try

{

student_info r = new student_info()

{

name = name,

age = age

};

en.student_info.Add(r);

en.SaveChanges();

return "Data saved successfully";

}

catch

{

return "1";

}

[HttpPost]

public string update(int id, string name, int age)

{

try

{

student_info st = en.student_info.FirstOrDefault(m => m.id == id);

if (st != null)

{

st.name = name;

st.age = age;

en.SaveChanges();

}

return "Data updated successfully";

}

catch

{

return "1";

}

Code for View:-

@model IEnumerable<mvcwithjson.Models.student_info>

Layout = null;

}
