Is there a way to override Ribbon Save Button functionality in publishing page of specific page layout? My intention is not to override it for all publishing pages but to limit it to specific page layout?
This is working fine in sharepoint list, but I have not tried in publishing page
You could a create a new control deriving from the original, and add it to a custom masterpage.
I don't know if it's wise to do this in a page layout because the ribbon is on the masterpage. jQuery would be a solution here, you could just add a script in a head content placeholder on your pagelayout to enable it there only.
