MVC Video :- Difference between viewdata,viewbag,tempdata and session.(MVC Interview questions)

See our other Step by Step video series below :-

In this MVC ( Model view controller) video we will try to understand what is the difference between viewdata,viewbag,tempdata and session.This is an interesting MVC interview question and below is a textual answer for the same.

Temp data: - Helps to maintain data when you move from one controller to other controller or from one action to other action. In other words when you redirect, "tempdata" helps to maintain data between those redirects. It internally uses session variables.

View data: - Helps to maintain data when you move from controller to view.

View Bag: - It's a dynamic wrapper around view data. When you use "Viewbag" type casting is not required.

you didn't test the same name in the viewbag controllers communication example, at minute eleven, you put ViewBag.CurrentDateTime while actually it was named ViewBag.CurrentDateANDTime.

Example is incorrect though concept is right.
CurrentDateAndTime and CurrentDateTime are different at 12:20

[rprabhuit]

wrong statement on TempData usage. TempData can be used from controller to view as well. The TempData will be reset to null, only after it was read or used. But we can keep the data's in TempData after read by calling TempData.Keep() function. The Keep() should be called immediately after TempData object used.

[JayadevNelli]

Very good video, thank you for posting.
