In this article I will explain with an example, how to render Partial View in jQuery as Html.RenderPartial and Html.Partial helper functions will not work with jQuery Client Side scripting.
The Partial View will be populated and fetched using jQuery AJAX and finally it will be rendered as HTML inside DIV using jQuery.
Database
This article makes use of the Microsoft’s Northwind Database. The download and install instructions are provided in the link below.
Configuring and connecting Entity Framework to database
Now I will explain the steps to configure and add Entity Framework and also how to connect it with the database.
You will need to add Entity Data Model to your project by right clicking the Solution Explorer and then click on Add and then New Item option of the Context Menu.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
From the Add New Item window, select ADO.NET Entity Data Model and set its Name as NorthwindModel and then click Add.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Then the Entity Data Model Wizard will open up where you need to select EF Designer database option.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Now the wizard will ask you to connect and configure the Connection String to the database.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
You will need to select the
1. SQL Server Instance
2. Database
And then click Test Connection to make sure all settings are correct.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Once the Connection String is generated, click Next button to move to the next step.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Next you will need to choose the Entity Framework version to be used for connection.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Now you will need to choose the Tables you need to connect and work with Entity Framework. Here Customers Table is selected.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
The above was the last step and you should now have the Entity Data Model ready with the Customers Table of the Northwind Database

Controller
The Controller consists of two Action methods.
Action method for handling GET operation
Inside this Action method, the Top 10 Customer records are fetched from the Customers Table of the Northwind Database and returned to the View.
Action method for handling jQuery POST operation
This Action method handles the call made from the jQuery POST function from the View.
The value of the customerId parameter is used to fetch the Customer record using Entity Framework which is then used to populate the Details Partial View.
Finally the Partial View is returned from the Controller.
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
NorthwindEntities entities = new NorthwindEntities();
return View(from customer in entities.Customers.Take(10)
select customer);
}
[HttpPost]
public ActionResult Details(string customerId)
{
NorthwindEntities entities = new NorthwindEntities();
return PartialView("Details", entities.Customers.Find(customerId));
}
}
View
Now you will need to Right Click inside the Controller class and click on the Add View option in order to create a View for the Controller.
The Name of the View is set to Index, the Template option is set to Empty, the Model class is set to Customer Entity (the one we have generated using Entity Framework) and finally the Data context class is set to NorthwindEntities.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Inside the View, in the very first line the Customer Entity is declared as IEnumerable which specifies that it will be available as a Collection.
For displaying the records, an HTML Table is used. A loop will be executed over the Model which will generate the HTML Table rows with the Customer records.
The last column of the HTML Table consists of an HTML Anchor Link. The HTML Anchor Link has been assigned a jQuery Click event handler.
When the HTML Anchor Link is clicked, a jQuery AJAX Call is made to the Details Action method of the Controller and the Details Partial View is fetched as HTML which is finally displayed using jQuery Modal Dialog Popup window.

Layout = null;

Partial View
In order to add Partial View, you will need to Right Click inside the Controller class and click on the Add View option in order to create a View for the Controller.
The Name of the View is set to Details, the Template option is set to Empty, the Model class is set to Customer Entity (the one we have generated using Entity Framework), the Data context class is set to NorthwindEntities and finally the Create as a partial view option needs to be checked.
![ASP.Net MVC: Using Html.RenderPartial and Html.Partial in jQuery for rendering Partial View]()
Inside the Partial View, in the very first line the Customer Entity is declared as Model for the Partial View. The details of the Customer is displayed using the Html.DisplayFor helper method.
@model Partial_View_MVC.Customer
<table cellpadding="0" cellspacing="0" border="0">
<tr>
<td valign="top"><b>@Html.DisplayNameFor(model => model.Address):</b></td>
<td>
@Html.DisplayFor(model => model.Address)
<br/>
@Html.DisplayFor(model => model.City),
@Html.DisplayFor(model => model.PostalCode)
<br/>
@Html.DisplayFor(model => model.Country)
</td>
</tr>
</table>
