We have implemented similar requirement i made few changes as per your need.

Let me know if that works for you.

a!localVariables(

RE: Read only Grid

The solution is probably to do some tricky post-processing on your local variable that holds your paged data set, inserting a fake row at the end for each page that contains the calculated value. I haven't tried this approach (at least not recently) so it may be more tricky and/or clunky than it's worth for you, but it's probably worth a try.
