Currently no – but it depends which is your server side language – PHP, ASP ….
In princip for every add/edit/delete the data is posted to the server. You will need to configure the url -where your save should be. In this file (or service) you should obtain the parameters from the post (you should known what to obtain) and save, update or delete the needed data.
As first step you need to known how to obtain parameters from ajax request in your prefered server language and how to make query's to the database.
Since jqGrid can be used with any server side language we do not provide examples of this, but it will be good to do in the future documentation.
