ViewState with AJAX in ASP.NET
Hi,
I have a page with AJAX enabled. I want to store some information on server side in the ViewState object as
ViewState("Key") = Value
Does this persists between the postbacks - because page is a partial rendering ? If it is not going to be persisted between the postbacks then what i need to do to get the value from ViewState ?
Thanks

Session is persisted.

Looks like the viewstate is not persisted. How bout a cookie instead?

A temporary solution to persist the viewstate, but still you're going to have the server doing the work.

If you're using updatepanels then the ViewState is persisted. The ViewState is passed back to the server when an ajax call is made and then passed back to the page.
In other words you can use ViewState as normal on a page with updatepanels but you should do so with caution: a large ViewState can slow the updatepanels to a crawl and make for a very frustrating user experience.

Needs to be in ViewState. I do not want the Session overhead on the server. BTW: Is Session is going to be persisted between the postbacks ?
Thanks
