This tutorial will teach you how to make a Inventory Management System in ASP.NET MVC with Ajax step by step. This system will helpful you to learn Inventory Management System.this system helpful for you learn sales handling process of asp.net mvc with ajax.
The System shall be able to find the barcode id of the products.in order to find the product details enter the barcode id in to the barcode id textbox then it will automatically find product details without loading page and produce the output in to the related textboxes.
This System shall be able to store the Sales details in to the SQLserver databases.after sales has been done.
The System shall be able to release the print receipt for print the bills.
First go and open the visual studio and create the new project.
After that Select the language as Visual C# with ASP.NET Web Application
Click Ok
Select MVC Click Ok
First we have to study MVC Folder of project MVC stands for model-view-controller.
i have attached the folder structure above(Models,Views,Controllers)
this course i am going to cover about database first approach.for deal with models folder first.
Create the database on the SQLserver.i have create database which name is possystem.
Product Table
Sales
Sales_product
these are the table you have create on the SqlServer. id set as primarykey along with auto increment.i have attach the screen shot image below. How to do it.
select the id column then go the id column properties below do it as Is Identity Yes.
After created the all the tables then go the the visual studio back.
select model folder and right click do the following steps i attached screenshot image below.
Select Data with ADO.NET Entity Data Model
Click Add after that pop up Generate from database click Next.
Establish the Database Connection
Configure the Connection Properties
select database name and give username and password while you installing the SQLserver. and test the connection
if the connection has success click OK Button.
Select the table
Click finish
Model.edmx diagram is created successfully.
After that select you project install the following libraries.
Newtonsoft.Json
jquery
bootstarp
After that select the home controller paste this code.i attached video tutorial below watch and do it.
go to the controller folder and double click the HomeController paste the following code
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WebApplication29.Models;
namespace WebApplication29.Controllers
{
public class HomeController : Controller
{
//you don't need this here except you want to use Dependency injection
possytemEntities10 dc = new possytemEntities10();
public ActionResult Index()
{
return View();
}
public ActionResult Print()
{
ajaxModel model = (ajaxModel)TempData["Data"];
//reassign temp data for reload purposes
TempData["Data"] = model;
return View(model);
}
[HttpPost]
public JsonResult Getid(String Id)
{
//Get the products from products sample collection for demo purpose.
//Get the products from the database in the real application
var std = dc.products.Where(a => a.id == Id).FirstOrDefault();
//return new JsonResult { Data = new { std = std } };
return Json(std, JsonRequestBehavior.AllowGet);
}
[HttpPost]
public JsonResult Save(string data)
{
ajaxModel model = JsonConvert.DeserializeObject<ajaxModel>(data);
bool status = false;
try
{
using (possytemEntities10 dc = new possytemEntities10())
{
//insert into Sales table
var sale = new sale
{
date = DateTime.Now.ToString("d"), //ToString was used because the date in the model was string
subtotal = model.total
};
dc.sales.Add(sale);
dc.SaveChanges();
model.data.ForEach(m =>
{
//get the product and deduct the subtotal
var db_product = dc.products.First(e => e.id == m.barcode);
db_product.qty = db_product.qty - m.qty;
dc.sales_product.Add(new sales_product
{
sales_id = sale.id,
product_id = int.Parse(m.barcode),
price = m.pro_price,
qty = m.qty,
total = m.total_cost
});
});
dc.SaveChanges();
status = true;
}
return new JsonResult { Data = new { status, message = "Entry saved successfully" } };
}
catch (Exception e)
{
return new JsonResult { Data = new { status, message = "There was an error saving the Entry" } };
}
}
[HttpPost]
public ActionResult SaveNew(string data)
{
ajaxModel model = JsonConvert.DeserializeObject<ajaxModel>(data);
bool status = false;
try
{
using (possytemEntities10 dc = new possytemEntities10())
{
//insert into Sales table
var sale = new sale
{
date = DateTime.Now.ToString("d"), //ToString was used because the date in the model was string
subtotal = model.total
};
dc.sales.Add(sale);
dc.SaveChanges();
model.data.ForEach(m =>
{
//get the product and deduct the subtotal
var db_product = dc.products.First(e => e.id == m.barcode);
db_product.qty = db_product.qty - m.qty;
dc.sales_product.Add(new sales_product
{
sales_id = sale.id,
product_id = int.Parse(m.barcode),
price = m.pro_price,
qty = m.qty,
total = m.total_cost
});
});
dc.SaveChanges();
model.date = sale.date;
model.orderId = sale.id;
status = true;
}
TempData["Data"] = model;
return new JsonResult { Data = new { status, message = "Entry saved successfully"} };
//return RedirectToAction("Print", model);
}
catch (Exception e)
{
return new JsonResult { Data = new { status, message = "There was an error saving the Entry" } };
}
}
public string sales_id { get; set; }
}
} After that go the views folder there is the folder which name Shared inside the Shared folder there is the file which name is layout.cshtml. this is the layout file.
Layout File
Layout file is a common file for each page. Example you have the header and footer in your website. header and footer are common for each pages.it called as layout.content would be changed each pages like about us pages displays regarding about us content,Contact us pages displays regarding Contact us content.like that.layout.cshtml paste the following codes.

@Styles.Render("~/Content/css")
@Scripts.Render("~/bundles/modernizr")
@RenderSection("styles", false)
</head>
<body>
<div class="container-fluid bg-2 text-center">
@RenderBody()
</div>
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
@RenderSection("scripts", required: false)
</body>
</html>
After done that go the view folder inside the views folder there is folder Home inside the home folder folder paste the following code.
index.cshtml
@{
ViewBag.Title = "Index";
}
<div class="row">
<div class="col-sm-8">
@using (Html.BeginForm("Index", "home", FormMethod.Post, new { id = "popupForm" }))
{
<table class="table table-bordered">

<input type="text" class="form-control" placeholder="total_cost" size="35px" id="total_cost" name="total_cost" disabled>
</td>
<td>
<button class="btn btn-success" type="button" >
after that create file print.cshtml paste the following code.
@using WebApplication29.Models
@model ajaxModel

var count = 0;
