Client side changes not reflected in page

Hi everyone! I have a hidden input field in a form which I change in some occasions on the client using javascript, but when I use "view source" I can't see these changes reflected on the page!

Does anyone know what I should do in order for the page to know the change?

(Tried with enableviewstate=false, true, whatever, didn't work)

I would like to have the change reflected in the page without doing a postback!
Is this possible? Thanks in advance!

Page Source doesn't change. Once it's loaded into the browser, any changes are just made in memory. If you want it reflected in the Page Source (and I don'tknow why you'd need it) you'll have to make a full round trip to the server.

yes but, on postback the field's value does not contain that value!

I'm not sure I understand what you mean. If you change a value on the client and post the form, the new value is passed back. Not the old one.

What are you trying to do?
