ActionLink to Details page linked by ID

Question

User982203039 posted

I am trying to add a actionlink to a details page. The link opens the page but with no results. Here is the detail of the  link:

@Html.ActionLink(item.FirstName, "Details", "Employees", new { id = item.ID }, null)

And the controller:

public ActionResult Details(int id)
{
Employee employee = db.Employees.Find(id);
if (employee == null)
{
return HttpNotFound();
}
return View(employee);
}

The link when hovering over it shows:Employees/Details/5

Does an employee with ID 5 exist?  Can you share the View markup?

Hi Baze72,

@Html.ActionLink(item.FirstName, "Details", "Employees", new { id = item.ID }, null)

And the controller:

public ActionResult Details(int id)
{//add a breakpoint on this line
Employee employee = db.Employees.Find(id);
if (employee == null)
{
return HttpNotFound();
}
return View(employee);
}

I suggest you could add breakpoint on highlight line,check if your id is passed over.

If no,maybe there are some wrong in your route,check your RouteConfig.cs.

if id has value,check if green line has value,

if employee ==null,it do will return HttpNotFound;

Best Regards.

Hi,

"no results" that is? Do you mean it shows a 404 not found or maybe an empty view ? Either the view doesn't properly show data or maybe the employee for this id does have empty fields?

Always start from what actually happens and then you read the code to understand why it happens (not to guess what is the thing that happens that you barrely described).
