In this article I will explain with an example, how to populate (bind) HTML Table from SQL Server database using jQuery AJAX and JSON in ASP.Net MVC Razor.
The HTML Table will also implement Paging (Pagination) using jQuery AJAX, JSON and Entity Framework in ASP.Net MVC Razor.
 
 
Database
Here I am making use of Microsoft’s Northwind Database. You can download it from here.
Download and install Northwind Database
 
 
Entity Framework Model
Once the Entity Framework is configured and connected to the database table, the Model will look as shown below.
Note: For beginners in ASP.Net MVC and Entity Framework, please refer my article ASP.Net MVC: Simple Entity Framework Tutorial with example. It covers all the information needed for connecting and configuring Entity Framework.

Model
The following Model class named CustomerModel consists of four properties.
1. Customers – List collection of the Customer Entity Data Model which will hold the records of the Customers.
2. PageIndex – Holds the value of the index of the Current Page.
3. PageSize – Holds the value of number of rows to be displayed per page.
4. RecordCount – Holds the value of the Total Records present in the Table.
public class CustomerModel
{
    public List<Customer> Customers { get; set; }
    public int PageIndex { get; set; }
    public int PageSize { get; set; }
    public int RecordCount { get; set; }
}
 
 
Controller
The Controller consists of two Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
 
Action method for handling jQuery AJAX operation
This Action method handles the call made from the jQuery AJAX function from the View.
Note: The following Action method handles AJAX calls and hence the return type is set to JsonResult.
 
First an object of the CustomerModel class is created and then the records are fetched from the Customers table using Entity Framework and are assigned to the Customers property of the CustomerModel object.
The Paging is performed on the records using the Skip and Take functions.
The Skip function accepts the Start Index from the set of records to fetched i.e. if Page Index is 1 then the Start Index will be (1 - 1) * 10 = 0.
Example: If Current Page Index is 1 and the Maximum Rows is 10 then the Start Index will be (1 - 1) * 10 = 0.
 
The Take function will fetch the rows based on the value of the PageSize property.
Finally, the CustomerModel object is returned to the View as JSON object.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public JsonResult AjaxMethod(int pageIndex)
    {
        NorthwindEntities entities = new NorthwindEntities();
        CustomerModel model = new CustomerModel();
        model.PageIndex = pageIndex;
        model.PageSize = 10;
        model.RecordCount = entities.Customers.Count();
        int startIndex = (pageIndex - 1) * model.PageSize;
        model.Customers = (from customer in entities.Customers
                           select customer)
                         .OrderBy(customer => customer.CustomerID)
                         .Skip(startIndex)
                         .Take(model.PageSize).ToList();
        return Json(model);
    }
}
 
 
View
The View consists of an HTML Table which will be populated with data from SQL Server database using jQuery AJAX and JSON.
The GetCustomers JavaScript function is called inside the jQuery document ready event handler and also when the Pager Button is clicked.
Inside the GetCustomers JavaScript function, the value of the PageIndex is sent to the Controller’s Action method using a jQuery AJAX call.
The Controller’s Action method returns a JSON object of the CustomerModel class which contains the List of Customers, the current Page Index, the Page Size and the total Record Count.
Using this JSON object and the dummy HTML row, the HTML Table is populated with the records returned by the Entity Framework.
The Pager is populated using the ASPSnippets_Pager jQuery Plugin.
