Very simple scenario...I have a form with a div that is initially displayed. I have a simple span with an "onclick" that toggles whether the div is displayed using the div's style.display attribute. The form also has controls on it that do ajax postbacks to update other controls. Let's say I hide the div client-side, then do an ajax postback. When the ajax postback is done, the div goes back to being displayed as it was when the form initially loaded. How can you maintain things that happen client-side with javascript after an ajax postback occurs. If I hide the div setting style.display = 'none' and then do an ajax postback, i want the div to still be hidden. Any help?
