Menu
I have one layout and one partial view which are in the Shared folder. Partial view presents top menu items which are not static. So I need to call an action method to get menu items from database. To do this, I created a controller and add an action method in it.
When I try to browse the page in web browser, this error occured:
The controller for path '/' was not found or does not implement IController.
Note: I tried Html.RenderAction, Html.Partial methods too... And I tried to create another view folder, and create a new partial view and new controller that named with "folder name + Controller" suffix.
Layout:
<!DOCTYPE html>
<html>
<head>
<title>@ViewBag.Title</title>
</head>
<body>
<div id="header">
@Html.Action("~/Views/Shared/_TopMenu.cshtml", "LayoutController", new {area =""}); //Here is the problem.
</div>
<div>
@RenderBody();
</div>
</body>
</html>
_TopMenu.cshtml:
@model IList<string>
@foreach (string item in Model)
{
<span>item</span>
}
LayoutController (in Controllers folder):
public class LayoutController : Controller
{
//
// GET: /Shared/
public ActionResult Index()
{
return View();
}
[ChildActionOnly]
[ActionName("_TopMenu")]
public ActionResult TopMenu()
{
IList<string> menuModel = GetFromDb();
return PartialView("_TopMenu", menuModel);
}
}

What happens if you put this in your view?
@{ Html.RenderAction("TopMenu", "Layout"); }
(And comment this out until everything works: //[ChildActionOnly])

Change this line,
@Html.Action("~/Views/Shared/_TopMenu.cshtml", "LayoutController", new {area =""});
to,
@Html.Action("_TopMenu", "Layout", new {area =""});
and check.

exist differents ways, for this case I like use html.action in layout, and in control I will create a string Menu, the string contains the html code I need, the controller end with return Content(menu);
for example
Layout:
<body>
<nav>
@Html.Action("_TopMenu", "Layout")
</nav>
the controller
public class LayoutController : Controller
{
public ActionResult _TopMenu()
{
IList<string> menuModel = GetFromDb();
string menu = "<ul>";
foreach(string x in menuModel)
{
menu +="<li><a href='"+x+"'>+x+"</a></li>";
}
menu+="</ul>";
return Content(menu);
}
}
I like that because I can use many options to create menus dinamics more complexes.
other way use ajax to recovered the data and use handlebars or other template for the code
