When I first load a page, I set a default value to the viewstate. Later, i changed that value with an asyncpost back. Then when I do another asyncpostback, the viewstate is the same value from when I set it in the pageload.

I am guessing that this is caused by the first asyncpostback just simply sending a call to the server, and not updating the viewstate on the page. How would I update the viewstate on the page from an asyncpostback?

c0rrupt,

It's an old technique, but you could always just use a HiddenField control to make sure your data element is always available through the async postback.
