Hi,

I have the following scenario:-
1) I have a web part
2) This web part uses a class library
3) In the Class Library I want to save and retrieve values from the ViewState

I am not able to do this since ViewState is always associated to a control.
What are the possible options with which I can achieve this?. I don’t want to
pass the instance of the web part in the class lib.

Thanks in advance

HttpContext.Current.CurrentHandler will give you a reference to the
currently running page. Once you have the page, you can use it's ViewState.

Hi Eliyahu,

Thanks for the reply.

I have one doubt with respect to the solution just provided:-

1) Web parts would developed independent of each other by developer and then
assembled on the page
2) If 2 developers of the web part coincidently have the same key for
storing values in web part

Wouldent that cause an issue?

One solution I can think of is each developer provide a prefix for the key’s
they use.

Is there a better way out caus we are now relying on the developer to
provide unique keys, which may not always be done ?

Thanks again for the reply.

Well, the original question was just about accessing the viewstate and your
new questions will apply for any solution.

I am not familiar much with webparts. If they provide a sort of unique id,
you could use this id as the prefix. In any case you may want to make a
utility method that will access the viewstate in the way you wish.
