Download Project  (Full Project)

Step-1

In this tutorial we make Order edit option by using  jQuery  in master detail page. Before watch this video you should watch part one. Now first open visual studio then open our project where we are working.  Then open SQL server management studio and add row name is id which database are use previse. This id is added into SQL database. This id are will be relation in customer table under customerId column. Now open .edmx file and update .edmx file and save it or rebuild our project. We can see the id is added here.  We can also see the .edmx file is update by add the id column. This  file also show the relation between tables. This is the visual representation of class and property. Database table name will be class name and database  row name will be property name. In this video we will  show product edit details. Now first create a model into model folder model name is MyOrderViewModel. In this model we will define some property like OrderId, ProductName, Quantity, Price, Amount, CustomerId,  Id etc like database model.  After that build the project. Now go to index view and comment the Edit link tag. Now write td tag and under td tag write a tag and write onclick method and under the method pass the order table of id.this onclick method are response the JavaScript code. In tr tag we  create a id in this id pass row  and also item.id. Now we write more td tag to pass the id but it does not show in this view so we write style display none. Now write some script code to pass order id and receive  the id in js code. Now create script function name is EditOrder it’s takes a parameter id which pass from item.id.  also this EditOrder function show bootstrap modal   by the modal of id. Before write script we must and should add jquiry script. Now build the solution. Now go to C# controller name is OrdersController in this controller we need to create a method name is EditOrder this method receive a id parameter. create a OrderViewModel object. Now by singleOrDefoult find order details then store in  or variable then  object initialize  the every fild of order table object. Now create a partial view and pass the model from the view. Name is partial view is partial1 and create a form in partial view  in this view add in div tag and under div tag use an loading image as .gif file. Then write some script. Now when run the project we can see the bootstrap modal popup and order edit field are display. In this modal by JavaScript pass the object in controller the method receive  the object and check and find the object from database. Then initialize the object field then call the db.savechange function. Now run the project and edit the product edit option.

Step-2

After that we create order class into model folder. This model name is MyOrderViewModel. In this class we add some property. Given bellow the model code:

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

namespace MasterDetailsDemo.Models
{
    public class MyOrderViewModel
    {
        public System.Guid OrderId { get; set; }
        public string ProductName { get; set; }
        public int Quantity { get; set; }
        public decimal Price { get; set; }
        public Nullable<decimal> Amount { get; set; }
        public System.Guid CustomerId { get; set; }
        public int Id { get; set; }
    }
} 

Step-3

Now go to index.cshtml page and  after amount comment the rezor button and create ‘td’  tag and under td tag create ‘a’  tag. Now we create ’script’ tag in script tag we write some js code. In this index file we need to add bootstrap modal. Also we have to add jquery reference. Given bellow the index.cshtml code:


@model IEnumerable<MasterDetailsDemo.Models.Customer>
@{
    ViewBag.Title = "Index";
}

<br /><br />
<div class="panel panel-default">
    <div class="panel-heading">
        <div class="row">
            <h2 class="panel-title pull-left" style="margin-left:10px;">
                <strong>Order Details</strong>
            </h2>
            <button style="margin-right:10px" class="btn btn-primary pull-right" onclick="addNewOrder()">New Order</button>
        </div>
    </div>

    @*Receive All Database Data From Controller And Display Those Data In Client Side*@
    <div id="accordion">
        @if (Model.Count() != 0)
        {
            foreach (var item in Model)
            {
                <h3>
                   Invoice No: #@item.Id

                    <span class="pull-right">order Date: @item.OrderDate

                    <a href="#" class="btn btn-success btn-xs" onclick="AddMoreOrder(@item.Id)"><i class="glyphicon glyphicon-plus"></i></a>

                <div>
                    <div class="row">

Step-4

Now go to order controller and create EditOrder method. In edit order controller we need to pass parameter like id. Under the controller we create OrderviewModel object  and iinitialize the constructor of this model. Now create Order model object and insert the database data into the Order momdel object.

Given bellow the OrderController code:

using MasterDetailsDemo.Models;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;

namespace MasterDetailsDemo.Controllers
{
    public class OrdersController : Controller
    {
        OnlineShopEntities db = new OnlineShopEntities();

        public ActionResult Index()
        {
        
                List<Customer> OrderAndCustomerList = db.Customers.OrderByDescending(s=>s.OrderDate).ToList();
            return View(OrderAndCustomerList);
        
        }

        [HttpPost]
        public ActionResult Index(MyOrderViewModel model)
        {
            if (model.Id > 0)
            {
                Order or = db.Orders.SingleOrDefault(x => x.Id == model.Id);

                or.Id = model.Id;
                or.ProductName = model.ProductName;
                or.Quantity = model.Quantity;
                or.Price = model.Price;
                or.Amount = model.Amount;
                db.SaveChanges();
            }

            return View(model);
        }





       
        public ActionResult AddMoreOrder(int Id)
        {
            MyOrderViewModel model = new MyOrderViewModel();

            Customer cus = db.Customers.SingleOrDefault(c => c.Id == Id);
            model.Id = cus.Id;
            model.CustomerId = cus.CustomerId;
            return PartialView("Partial2", model);

        }


        public ActionResult AddMoreOrderSave(MyOrderViewModel model)
        {
            Order or = new Order();
            or.OrderId = Guid.NewGuid();

            or.ProductName = model.ProductName;
            or.Quantity = model.Quantity;
            or.Price = model.Price;
            or.Amount = model.Amount;
            or.CustomerId = model.CustomerId;
            db.Orders.Add(or);
            db.SaveChanges();
            return View(model);

        }


        public ActionResult SaveOrder(string name, String address, Order[] order)
        {
          
                string result = "Error! Order Is Not Complete!";
            if (name != null && address != null && order != null)
            {
                var cutomerId = Guid.NewGuid();
                Customer model = new Customer();
                model.CustomerId = cutomerId;
                model.Name = name;
                model.Address = address;
                model.OrderDate = DateTime.Now;
                db.Customers.Add(model);

                foreach (var item in order)
                {
                    var orderId = Guid.NewGuid();
                    Order O = new Order();
                    O.OrderId = orderId;
                    O.ProductName = item.ProductName;
                    O.Quantity = item.Quantity;
                    O.Price = item.Price;
                    O.Amount = item.Amount;
                    O.CustomerId = cutomerId;
                    db.Orders.Add(O);
                }
                db.SaveChanges();
                result = "Success! Order Is Complete!";
            }
            return Json(result, JsonRequestBehavior.AllowGet);
          
        }



        public ActionResult EditOrder(int Id)
        {
            MyOrderViewModel model = new MyOrderViewModel();

            Order or = db.Orders.SingleOrDefault(c => c.Id == Id);
            model.Id = or.Id;
            model.ProductName = or.ProductName;
            model.Quantity = or.Quantity;
            model.Price = or.Price;
            model.Amount = or.Amount;
            model.CustomerId = or.CustomerId;
            return PartialView("Partial1", model);
        }



        // GET: Order/Edit/5

            ViewBag.CustomerId = new SelectList(db.Customers, "CustomerId", "Name", order.CustomerId);

        }

    }
}

Step-5

In this model we create a partial view. This code auto implemented. In this section we add a image in img tag.  given bellow the code :

@model MasterDetailsDemo.Models.MyOrderViewModel

<div>
    <form id="myForm1">
        @Html.HiddenFor(m => m.Id)

        <div class="form-group">
            <label for="exampleInputEmail1">Product Name</label>
            @Html.TextBoxFor(model => model.ProductName, new { @class = "form-control", @placeholder = "Name" })
        </div>
        <div class="form-group">
            <label for="exampleInputEmail1">Quantity</label>
            @Html.TextBoxFor(model => model.Quantity, new { autocomplete = "off", @class = "form-control", @placeholder = "Address", @id = "txtQuantity1" })
        </div>
        <div class="form-group">
            <label for="exampleInputEmail1">Price</label>
            @Html.TextBoxFor(model => model.Price, new { autocomplete = "off", @class = "form-control", @placeholder = "Address", @id = "txtPrice1" })
        </div>
        <div class="form-group">
            <label for="exampleInputEmail1">Amount</label>
            @Html.TextBoxFor(model => model.Amount, new { @class = "form-control", @placeholder = "Address", @id = "txtAmount1", @readonly = "readonly" })
        </div>
        <hr />
        <a href="#" id="btnSubmit" class="btn btn-success btn-block">
            <span>Update</span>

        </a>


    </form>
    <div style="text-align:center;display:none" id="loaderDiv1">
        <img src="~/loadings.gif" width="150" />
    </div>

</div>

<script>

    $(document).ready(function () {


        $("#btnSubmit").click(function () {
            $("#loaderDiv1").show();
            var myformdata = $("#myForm1").serialize();

            $.ajax({

                data: myformdata,
                success: function () {
                    alert("Product Updated");
                    $("#loaderDiv1").hide();
                    $("#myModal").modal("hide");
                    window.location.href = "/Orders/Index";
                },
                error: function () {
                    alert("Product Updated")

                }
            })

        })

    })


    $(document).ready(function () {

        $("#txtQuantity1,#txtPrice1").keyup(function (e) {

            var q = $("#txtQuantity1").val();
            var p = $("#txtPrice1").val();
            var result = "";
