MVC5 Getting a button to call an action method in Controller

Question

As the heading states when I click a button on my main view I need it to call a method in my controller for that view. Ive been trying for hours and Ive changed the specific lines of code many times but all variations seem to give the same errors so im just showing the simplest versions to get my point across. Everytime I try something I get a 404 error that the path is not found. So im assuming something is wrong with the code in my view. Im not using JQuery or any javascipt

The line of code in my index view:

@Html.ActionLink("Button4Pressed", "Button4Pressed", "HomeController");

I know this wont work for getting methods but it works for changing pages so I thought I would start there. Im not sure if I should be doing it as a href or button.

my method in my HomeController:

 [HttpPost]
    public ActionResult Button4Pressed()
    {
        state = "year";
        MyChart();
        return View();
    }

heres my Solution Explorer

Im pretty new to MVC and propably doing some pretty stupid stuff so any help is appreciated thanks.

You have two options:

Option A

Remove the [HttpPost] attribute from your controller method and you will be able to create normal links to it, i.e. with @Html.ActionLink()

Option B

Keep the [HttpPost] attribute and use a form or ajax to send the request as a HTTP Post request, i.e.

<form id="Button4Pressed" action="@Url.Action("Button4Pressed", "Home")" method="post"></form>
<a href="#" onclick="javascript:document.getElementById('Button4Pressed').submit()">Button4</a>
