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.

When the hyperlink is clicked, the user will be redirected to employee details page, displaying the full details of the employee as shown below.

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();
// Replace square brackets with angular brackets
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 the point, “Index.cshtml” view should be generated. Copy and paste the following code in “Index.cshtml”.
@* Replace square brackets with angular brackets *@
@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”)
