One of the best articles you can refer for this and better understanding:
ViewBag Vs ViewData Vs TempData Vs Session[^]

Hope this clears your concept here.
Thanks

ViewData acts like a collection you add things to, whereas ViewBag is a dynamic type so you simply set and read properties on it. ViewData was conceived before dynamic types were implemented so it was a way of holding a collection of objects you could define at run-time.

The only real difference is the syntax. ViewBag is the latest version and has, in a way, superseded ViewData as it uses technology that wasn't around when ViewData was implemented. Just use whichever looks\feels better to you, and whichever you prefer.
