How To Dynamically Load Employee Details In jQuery Popover Using MVC 5

Introduction

In this article, I will demonstrate how to dynamically load employee details using MVC 5 and Entity Framework. I will also load employee details in bootstrap popover based on their Id and will also use jQuery data table for searching, sorting, and paging.

Step 1

Open SQL server 2014 and create a database table. 

  1. CREATE TABLE [dbo].[Employee](  
  2.     [ID] [int] IDENTITY(1,1) NOT NULL,  
  3.     [Name] [nvarchar](50) NULL,  
  4.     [Position] [nvarchar](50) NULL,  
  5.     [Office] [nvarchar](50) NULL,  
  6.     [Age] [intNULL,  
  7.     [Satrt_Date] [dateNULL,  
  8.     [Salary] [nvarchar](50) NULL,  
  9.  CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED   
  10. (  
  11.     [ID] ASC  
  12. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ONON [PRIMARY]  
  13. ON [PRIMARY]  
  14.   
  15. GO  

Step 2

Open Visual Studio 2015, click on New Project and create an empty web application project.

After clicking OK, the project will be created with the name of MvcDynamicallyLoadContent_Demo.

Step 3

Add Entity Framework now. For that, right click on Models folder, select Add, then select New Item, then click on it.

  1. namespace MvcDynamicallyLoadContent_Demo.Models  
  2. {  
  3.     using System;  
  4.     using System.Collections.Generic;  
  5.       
  6.     public partial class Employee  
  7.     {  
  8.         public int ID { get; set; }  
  9.         public string Name { get; set; }  
  10.         public string Position { get; set; }  
  11.         public string Office { get; set; }  
  12.         public Nullable<int> Age { get; set; }  
  13.         public Nullable<System.DateTime> Satrt_Date { get; set; }  
  14.         public string Salary { get; set; }  
  15.     }  
  16. }  

Step 4

Right click on Controllers folder, select Add, then choose Controller as shown in below screenshot.

ASP.NET

 

After clicking on the controller a window will appear to choose MVC5 Controller-Empty click on Add.

ASP.NET

 

After clicking on Add another window will appear with DefaultController. Change the name to HomeController then click on Add. HomeController will be added under Controllers folder. Remember don’t change the Controller suffix for all controllers, change only highlight, and instead of Default just change Home as shown in the below screenshot.

ASP.NET

 

Complete code for controller 

  1. using MvcDynamicallyLoadContent_Demo.Models;  
  2. using System;  
  3. using System.Collections.Generic;  
  4. using System.Linq;  
  5. using System.Web;  
  6. using System.Web.Mvc;  
  7.   
  8. namespace MvcDynamicallyLoadContent_Demo.Controllers  
  9. {  
  10.     public class HomeController : Controller  
  11.     {  
  12.         // GET: Home  
  13.         public ActionResult Index()  
  14.         {  
  15.             List<Employee> employeeList = new List<Employee>();  
  16.             using (DBModel db=new DBModel ())  
  17.             {  
  18.                 employeeList= db.Employees.ToList();  
  19.             }  
  20.               return View(employeeList);  
  21.         }  
  22.   
  23.         public ActionResult EmployeeDetails(int id)  
  24.         {  
  25.             using (DBModel db=new DBModel())  
  26.             {  
  27.                 List<Employee> employee = db.Employees.Where(x => x.ID == id).ToList();  
  28.                 return View(employee);  
  29.             }  
  30.         }  
  31.     }  
  32. }  

Step 5

Right-click on index action method in the controller. Add view window will appear with default index name unchecked (use a Layout page) and click on Add as shown in the below screenshot. View will be added in views folder under Home folder with name index.
