I have created a Single Page Application (ASP.NET MVC4) using Steven Sanderson’s instructions. The issue I’m currently seeing is that whenever I edit an item and save the changes, Upshot sends the whole item back to the server and not only the modified properties as it would be expected. (I know this because firebug can inspect what is being sent to the server).

I’m pretty sure that upshot should be able to send only the modified properties as it uses knockout observables so it can keep track of what’s changed and what’s not.

My question is, is this possible at the moment (maybe some kind of configuration parameter) or should I wait for a future version to implement this? Upshot is a rather new library so finding documentation is pretty hard right now.

    At the moment, upshot is only able to submit the entire object to the server. It was designed to work with the SPA DataController, whose Submit method takes as an input parameter a ChangeSet – exactly what upshot sends through the wire. (the original entity, the changed entity and the operation that was performed – e.q. 2 for Update).

    However, both upshot and the DataController have been put on hold by the Microsoft Team, so it might take a while for a new version to appear.

    Update

    You can find the reference here. They talk about putting the SPA project “on pause” for the time being. If you check out the source code, you’ll find that upshot is a part of the SPA package, and that neither upshot nor the DataController have been included in the RC release.
