In this video we will discuss, generating hyperlinks using actionlink html helper, for navigation between MVC pages. 

Please watch Part 8, before proceeding.



We want to display all the employees in a bulletted list as shown below. Notice that all the employee names are rendered as hyperlinks.
Adding Links between pages using html helpers

When the hyperlink is clicked, the user will be redirected to employee details page, displaying the full details of the employee as shown below.
Generate links using Html.ActionLink html helper

Copy and paste the following Index() action method in EmployeeController class. This method retrieves the list of employees, which is then passed on to the view for rendering.
public ActionResult Index()
{
    EmployeeContext employeeContext = new EmployeeContext();
    List<Employee> employees = employeeContext.Employees.ToList();

    return View(employees);
}

At the moment, we don't have a view that can display the list of employees. To add the view
1. Right click on the Index() action method
2. Set
View name = Index
View engine = Razor
Select, Create a stronlgy-typed view checkbox
Select "Employee" from "Model class" dropdownlist
3. Click Add

At this point, "Index.cshtml" view should be generated. Copy and paste the following code in "Index.cshtml".
@model IEnumerable<MVCDemo.Models.Employee>

@using MVCDemo.Models;

<div style="font-family:Arial">
@{
    ViewBag.Title = "Employee List";
}

<h2>Employee List</h2>
<ul>
@foreach (Employee employee in @Model)
{
    <li>@Html.ActionLink(employee.Name, "Details", new { id = employee.EmployeeId })</li>
}
</ul>
</div>

Points to Remember:
1. @model is set to IEnumerable<MVCDemo.Models.Employee>
2. We are using Html.ActionLink html helper to generate links

Copy and paste the following code in Details.cshtml
@Html.ActionLink("Back to List", "Index")

    1. EmployeeContext class derives from DbContext class, and is responsible for establishing a connection to the database

  7. Dear sir,

    Many thanks for your videos. It is quite useful. I am not a programmer - but these videos help me to shift my career to programmer. While following this video I am getting cannot implicitly convert type 'System.collection.Generic.List' to System.Web.MVC.ActionResult. It would be helpful if you can give your inputs - if possible. I using the same entity objects as you are doing.
    Cheers
    Sathya
