ASP.Net MVC Controller for _Layout

Question

I am working on a dynamic menu system for MVC and just to make it work, I created a partial view for the menu and it works great using the syntax below:

@Html.RenderPartial("_Menu", (Models.Menu)ViewBag.MainMenu)

BUT, to do so, I would have to set the MainMenu and FooterMenu (or any other menu for that matter) in the ViewBag on each Controller and each action. To avoid this, I was wondering if there was a recommended event that I could access the ViewBag globally. If not, does anyone recommend passing the Menu object into a session variable? It doesn't sound right to me, but only thing I can think of right now.

UPDATE:

_Layout.cshtml - I included the new call to Action:

@Html.Action("RenderMenu", "SharedController", new { name = "Main" })

SharedController.cs - Added New Action:

public ActionResult RenderMenu(string name)
{
    if (db.Menus.Count<Menu>() > 0 && db.MenuItems.Count<MenuItem>() > 0)
    {
        Menu menu = db.Menus.Include("MenuItems").Single<Menu>(m => m.Name == name);
        return PartialView("_MenuLayout", menu);
    }
    else
    {
        return PartialView("_MenuLayout", null);
    }
}

And it throws the following exception:

The controller for path '/' was not found or does not implement IController.

UPDATE 2:

So, the issue is that I referenced the Controller by the full name and you only need the name of the controller minus "Controller". Neat tidbit. So, for my example, this works:

@Html.Action("RenderMenu", "Shared", new { name = "Main" })

set your menu up as an action then call it in your master layout.

use @Html.Action()

the action can return a partial view with your menu code in it.

wow, I knew it was something simple, but didn't know all of the ins-and-outs of MVC yet. Thanks so much Matt!

Nevermind...so sorry, I updated my code yet again. The problem was that I was including the full name of the controller when I only needed "Shared"
