InfoPath Dev

I have an InfoPath form designed in 2010 and have created a save as button.  I also have a submit button but it needs to be disabled before all fields are filled out.  Is there an easy way to get this done?

 Put the button inside a section and hide the section until all other fields are filled out using rules.  If you are showing the ribbon, don't and recreate the save and submit buttons.

Since you need all fields to be filled out, just mark them all as mandatory and it will fail validation on submit and tell them they need to fill out all fields. No need to even mess with the submit button, and fields are all marked in red indicationg mandatory before they even think of submitting.

 Depending on how you have your submitting set up  a straight forward 'make mandatory' doesn't work for a form
