I have an asp.net 3.5 update panel and I have a few textboxes that users enter information into that I want to persist when they return next time. I’ve tried various approaches to persisting the cookie from the click event of a button (postback trigger) etc. but I believe the problem is that there is no response header access during the ajax callback? Not sure!
How can I persist values of a textbox to a cookie that exist within the content of an asp.net update panel?
Thank you.
I ended up just creating a serializable class that I persist.
