Does the javascript grid control just manipulate the contents of the
DOM? If so, can you not just POST your revised data to the server
(standard http post). Or if you needed more frequent data transfer
you could probably have a javascript timer that uses AJAX to send the
data to the server.
That was my first hope. No, the JS grid does not just maintain a <table/>.
If it did, then the scaffold generated <% link-to ;action =>'update' %> would
have worked out of the box.
I suspect that I will need to use some AJAX type programming techniques. I
would certainly not object to getting my feet wet in that direction.
