A better approach than loading associations into ViewData

gistfile1.cs

//Loading associations into ViewData
public ActionResult Edit(Guid id) 
{
   var model = Repositories.Model.GetById(id);
   ViewData["Association"] = model.Association; //Gah! Magic Strings
   return View(model);
}

//In the view:
Html.Grid<AssociationType>(
     "Association", //Magic strings here too!
     new Hash(empty => "There are no associations"),
	 column => {
                 column.For(p => p.Name);
                 column.For(p => p.Value);
                });

gistfile2.cs

//A better approach: navigate to the associations off the model
public ActionResult Edit(Guid id) 
{
   return View(Repositories.Model.GetById(id)); //Ahhh, much neater.
}

//In the view:
Html.Grid(Model.Association, //And we didn't even need to specify the type here. Type Inference works.
    new Hash(empty => "There are no associations"),
	column => {
                column.For(p => p.Name);
                column.For(p => p.Value);
               });
