What is the best way to code the following:

I have a user form with various input controls. The user fills them out, clicks submit and the data from the form is inserted into the database. I would like to show an "Adding record to database" message as the data is being processed, then hide the form and show a confirmation panel. I have done this in the pass with AJAX using an UpdatePanel, but would like to try and get this to work with the CallbackPanel. I am also using Required Validation controls so I would like that to fire first, if Valid then insert data and show confirmation. If error then show error message on top of the form. I have code for inserting into database and gathering info from the form. Just not sure when or how to use CallbackPanel control, hiding-showing Panel controls and handling validation.

Thanks.
