IMHO using datatype json will return the data in json format and not post it as json. For more info refere to jQuery ajax paramaters.

You can use onclickSubmit event for this purpose. This event should return array which is passed to the request.

contentType: 'application/json; charset=utf-8',

datatype: 'json',

I've gone in grid.formedit.js to force the ajax calls to have these two and now the headers are OK, but the POST payload is not in JSON format:

Date=2008-01-01&Payee=Expensive+payee&ExpenseType=Production&Description=This+is+a+test+description+edited
&Amount=2500&id=79953eca-7f1b-4f96-aede-79518c2964c9&oper=edit

Is there an elegant way for me to intercept the form edit SUBMIT click and send my own AJAX request in the proper format?

I don't want to start mucking in the jqGrid core too much and I'd rather deal with within my own application.

BTW, I'm using a function datatype in thegrid to get jqGrid to work with .NET service but there doesn't seem o be an equivalent hook for the default (or custom) pager edit/add/del buttons.
