Access Viewbag property on all views

Question

How can I access some ViewBag properties across all my views? I want to have some information like current user name, etc accessible everywhere, but without having to to specifically define the properties in each ActionResult method on my project

Answer 1

The best and straight forward way to accomplish your requirement is to make a Custom Base Controller and inherit your Controller from this Base Controller.

public class MyBaseController : Controller
{
    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        ViewBag.someThing = "someThing"; //Add whatever
        base.OnActionExecuting(filterContext);
    }
}

Now instead of inheriting Controller class,inherit MyBaseController in your Controller as shown :-

public class MyOtherController : MyBaseController 
{
    public ActionResult MyOtherAction()
    {
       //Your Stuff
       return View();
    }
    //Other ActionResults
}
