Solution 1

1.View state is a cache for storing temp data between postbacks.

2.The data are stored/get from there based on a given unique key.

3.You can store any object inside it, even that object is created by using generics, but when you get the data from the cache you must convert it to its real type like in the next example:

C#

//Supposing that you have a generic list
GenericList<T> myList;
myList = new new GenericList<MyClass>();
//.. code to populate the list
//...
//Caching the list into the view state.
ViewState["MyGenericList"] = myList;
//...
//Getting the cached data from the view state.
var myData = (GenericList<MyClass>)ViewState["MyGenericList"]; //Must use conversion!

Answer to even such a point less question? And IMO, this is not even a question.

This is not a question.

Because the originator forgot to put the question sign, this doesn't mean that is not a question!

this question was asked in accenture

I don't care whether there is question mark or not. I just wanted to convey that there is no effort at all. No problem,issue,code explained. Now a days, we are facing too much such questions. If we won't train them to try something, situation will get worse in upcoming days.

This was my personal opinion and i just suggested you to encourage members to at least make some google search(Even same is stated on right pane when you post the question)

OK, I agree with you that in general, the question originators should try to give us as much context info is possible.
