Passing data to the master page

In this recipe, we are going to take a look at how to pass data down to the master page. While we could pass data from a normal ActionResult to the view via the ViewData dictionary and then have the MasterPage use that data, we won't as that creates a lot of redundant code spread out over multiple actions in the controller. We could alleviate some of this action code and move it up to the OnActionExecuted method in our controller. However, if our master page is shared across multiple controllers, then this too wouldn't be a good solution. For that reason, we will instead create a controller base class and use that for creating the data for our master page.

How to do it...

1. The first step is to create a new MVC application.
2. Next, we will create a controller base class called BaseController. In this base controller, we will initiate a list of data for navigational purposes.
Models/BaseController.cs:
```
public class BaseController : Controller
{
public BaseController...
```
