Sync Mulitple Devices Using Same Form

Question

I am developing a web based vehicle checkout form in which multiple users can log into the same form and perform the checkout for the same vehicle. The form contains approximately 100 checkboxes and is split up into 6 or so sections.

I was going to use update panels per section, to allow users to post back the results of their section of the checkout. My problem is that I need the other's that are logged into that same checkout need to see the sections update in real time, as the other users post the results of their sections.
For this function I was thinking of using a Timer control and updating pages every 30 seconds; however, I don't want to update the whole page because this will take focus away from checkboxes that the current users are focused on. How would I update the other user's without them losing focus on the current section that they are working in?

Any suggestions or help is greatly appreciated.

Thank you,

Hi @Denny Munson ,
There is a trigger in the update panel.It use AsyncPostBackTrigger to cause a partial page update.
