Menu
I have a multi-level Layout master pages in an ASP.NET MVC 4.
I have the following:
<title>@ViewBag.Title</title>
The order of Layout pages is as follows:
I am setting the @ViewBag.Title inside Index Action. However, I get the following exception:
Value cannot be null or empty. Parameter name: contentPath
Here is the code I have. I am simply making the code of ASP.NET Design Patterns books work for VS 2012 / MVC 4
_Layout.cshtml

This piece of code is throwing the exception: <a href="@Url.Content("")">. This happens because contentPath parameter of Url.Content method cannot be null or empty.
