Using Bootstrap Modal window as PartialView in .Net MVC

In this tutorial, we will walk you through the process of rendering a partial view as a Bootstrap modal in a .NET MVC application. This approach allows you to display additional information or details in a pop-up modal, improving the user experience and keeping the main page clutter-free. We will utilize the power of ASP.NET MVC, Bootstrap, and AJAX to achieve this functionality seamlessly.

Prerequisites

Before we begin, ensure you have the following prerequisites in place:

  • Basic knowledge of ASP.NET MVC and Bootstrap.
  • Visual Studio installed on your machine.
  • Familiarity with C# and Razor syntax.

Setting up the Project

  1. Launch Visual Studio and create a new ASP.NET MVC project.

  2. Install Bootstrap via the NuGet package manager. Open the Package Manager Console and run the following command:

Install-Package bootstrap
  1. Define the classes for Employee and EmployeeDetail in your model. These classes will represent the data structure for our tutorial.
// Employee class
public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
    public EmployeeDetail EmployeeDetail { get; set; }
}

// EmployeeDetail class
public class EmployeeDetail
{
    public int Age { get; set; }
    public string Email { get; set; }
    public int Experience { get; set; }
}

Creating the View

  1. Add a new view to display the list of employees. In your "Views" folder, create a new file named "Index.cshtml" and add the following content:
@model List<Employee>

<h2>Employee List</h2>

@foreach (var employee in Model)
{
    <p>@employee.Name</p>
    <button class="btn btn-primary" onclick="openModal(@employee.Id)">View Details</button>
}

<!-- Bootstrap Modal -->
<div class="modal fade" id="employeeModal" tabindex="-1" role="dialog" aria-labelledby="employeeModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="employeeModalLabel">Employee Details</h5>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
            <div class="modal-body" id="modalBody">
                <!-- The partial view content will be inserted here -->
            </div>
        </div>
    </div>
</div>

@section Scripts {
    <script>
        function openModal(employeeId) {
            $.ajax({
                url: '/Employee/GetEmployeeDetail',
                type: 'GET',
                data: { id: employeeId },
                success: function (data) {
                    $('#modalBody').html(data);
                    $('#employeeModal').modal('show');
                },
                error: function () {
                    alert('Error occurred while fetching data.');
                }
            });
        }
    </script>
}

Creating the Controller

  1. Add an "EmployeeController" to your project. Right-click on the "Controllers" folder, select "Add," and choose "Controller." Name it "EmployeeController.cs" and add the following code:
public class EmployeeController : Controller
{
    // Replace this method with your actual data retrieval logic
    private List<Employee> GetSampleEmployeeData()
    {
        return new List<Employee>
        {
            new Employee { Id = 1, Name = "John Doe", EmployeeDetail = new EmployeeDetail { Age = 30, Email = "[email protected]", Experience = 5 } },
            new Employee { Id = 2, Name = "Jane Smith", EmployeeDetail = new EmployeeDetail { Age = 28, Email = "[email protected]", Experience = 4 } }
        };
    }

    public ActionResult Index()
    {
        var employees = GetSampleEmployeeData();
        return View(employees);
    }

    // Action to return the partial view with EmployeeDetail data
     public PartialViewResult GetEmployeeDetail(int id)
        {
            // Replace this with your actual data retrieval logic
            //var employee = GetSampleEmployeeData().FirstOrDefault(e => e.Id == id);

            var employee = new Employee
            {
                Id = 1,
                Name = "John Doe",
                EmployeeDetail = new EmployeeDetail
                {
                    Age = 30,
                    Email = "[email protected]",
                    Experience = 5
                }
            };
            return PartialView("_EmployeeDetail", employee);
        }
}

Creating the Partial View

  1. In the "Views/Shared" folder, create a new file named "_EmployeeDetail.cshtml" and add the following content:
@model EmployeeDetail

<div class="employee-details">
    <h4>Name: @Model.Name</h4>
    <p>Age: @Model.Age</p>
    <p>Email: @Model.Email</p>
    <p>Experience: @Model.Experience years</p>
</div>

Note:

Remember to add reference to Jquery and Bootstrap JS Files.

Output:

 


Now your application should be able to display employee details in a Bootstrap modal when you click the "View Details" button for each employee. This approach offers a cleaner and more interactive way of displaying additional information without navigating away from the main page.
