ASPNet MVC Show selected Row details in Bootstrap Modal Popup

In this article I will explain with an example, how to show selected Row details in Bootstrap Modal Popup 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

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.

From the Add New Item window, select ADO.NET Entity Data Model and set its Name as NorthwindModel and then click Add.

Then the Entity Data Model Wizard will open up where you need to select EF Designer database option.

Now the wizard will ask you to connect and configure the Connection String to the database.

You will need to select the

1. SQL Server Instance

2. Database

And then click Test Connection to make sure all settings are correct.

Once the Connection String is generated, click Next button to move to the next step.

Next you will need to choose the Entity Framework version to be used for connection.

Now you will need to choose the Tables you need to connect and work with Entity Framework. Here Customers Table is selected.

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 AJAX 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.

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 Table 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 Bootstrap Modal Popup window.

Note: For more details on how to use jQuery AJAX for calling Controller’s Action method in ASP.Net MVC, please refer my article ASP.Net MVC: jQuery AJAX and JSON Example.

@model IEnumerable<Partial_View_MVC.Customer>

Layout = null;

}

<!DOCTYPE html>

<html>

<head>

<title>Index</title>

</head>

<body>

<h4>Customers</h4>

<hr/>

<tr>

<th>CustomerID</th>

<th>Contact Name</th>

<th>Country</th>

</tr>

@foreach (Customer customer in Model)

{

<tr>

<td>@customer.CustomerID</td>

<td>@customer.ContactName</td>

<td>@customer.City</td>

<td>@customer.Country</td>

</tr>

}

</table>

<h5 class="modal-title">Customer Details Form</h5>

</button>

</div>

</div>

<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>

</div>

$(function () {

$("#CustomerGrid .details").click(function () {

var customerId = $(this).closest("tr").find("td").eq(0).html();

$.ajax({

type: "POST",

url: "/Home/Details",

data: '{customerId: "' + customerId + '" }',

contentType: "application/json; charset=utf-8",

dataType: "html",

success: function (response) {

$("#partialModal").find(".modal-body").html(response);

$("#partialModal").modal('show');

failure: function (response) {

alert(response.responseText);

error: function (response) {

alert(response.responseText);

}

});

</script>

</body>

</html>

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.

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

<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>
