Populate (Bind) DropDownList from ViewBag in ASP.Net MVC

Here Mudassar Ahmed Khan has explained with an example, how to populate (bind) DropDownList from ViewBag in ASP.Net MVC Razor. The records from the database will be populated into a Generic List collection of Model class objects and then will be saved into a ViewBag object. Inside the View, the ViewBag object will be passed to the Html.DropDownList Helper function for populating the DropDownList in ASP.Net MVC Razor.
