Enable/Disable asp:validators using jquery

I am working with a wizard, where the user can sign up. There is a asp:RadioButtonList with two options, and some of the input fields in the wizard changes when the radiobutton changes. On each field there is some asp:Validators (asp:RequiredFieldValidator for example). The problem is, that when the user submits the page, the validator for the hidden textbox is still popping up.

Keep the current jQuery accordion pane open after ASP.NET postback?

I have a jquery accordion on an asp.net aspx weppage. Inside the panes, I have asp.net buttons. When I click on the button, the pane I was in, closes and reloads the page, defaulting to the first pane. I don’t mind the reload, but is there a way to keep the current pane open after the reload. Right now, I am just calling accordion() on a div with the id of accordion.
