# Whatt's the difference between ViewData and ViewBag?

I saw the [ViewBag](https://www.mindstick.com/forum/155739/define-viewbag-in-mvc) in [MVC](https://www.mindstick.com/forum/155803/define-cache-profile-in-mvc) 3. How's that different than [ViewData](https://www.mindstick.com/forum/12798/there-is-no-viewdata-item-of-type-ienumerable-selectlistitem-that-has-the-key-username) in MVC 2?

**ViewData & ViewBag objects**

**\****· ViewData**

## \

ViewData is a dictionary object that you put data into, which then becomes available to the view. ViewData is a derivative of the ViewDataDictionary class, so you can access by the familiar "key/value" syntax.

## · ViewBag

The ViewBag object is a wrapper around the ViewData object that allows you to create dynamic properties for the ViewBag.
