How to set ViewBag properties for all Views without using a base class for Controllers?

Question

In the past I\'ve stuck common properties, such as the current user, onto ViewData/ViewBag in a global fashion by having all Controllers inherit from a common base controlle

Answer 1

You could use a custom ActionResult:

public class  GlobalView : ActionResult 
{
    public override void ExecuteResult(ControllerContext context)
    {
        context.Controller.ViewData["Global"] = "global";
    }
}

Or even a ActionFilter:

public class  GlobalView : ActionFilterAttribute 
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        filterContext.Result = new ViewResult() {ViewData = new ViewDataDictionary()};

        base.OnActionExecuting(filterContext);
    }
}

Had an MVC 2 project open but both techniques still apply with minor changes.
