What makes the ViewState to support the textbox enter key to do a form post? I have a form with a save button at the bottom. If I click on that, this will make a post. But, an enter key on a textbox field will also trigger a post. However, if I save that page locally, under a.html, for example, and remove the ViewState portion, the enter key press is no longer supported.

The reason I ask is because I have pages which contain the ViewState at 100%. However, not all of them are supporting the textbox enter key for the post. So, there has to be something specific in a few pages.
