I'm still struggling with the date format that jqgrid returns to my web api.

The server exports dates in ISO8601-format that jqgrid processes fine: sorting goes well and the cells display the expected “dd/mm/yyyy”-format.

datefmt: 'ISO8601Short',
formatoptions: { srcformat: 'ISO8601Short', newformat: 'd/m/Y' }

I want to send back in ISO8601-format but jqgrid can only post the same format as displayed – as far as I understand the documentation.

Fiddler-tests proof that my server (ASP.NET MVC4 WEB API) accepts ISO8601-dates correctly. In the current configuration “dd/mm/yyyy”-dates are posted and the jsonparser switches day and month.

It would be a good to differentiate the screen and post format for dates. Another approach would be to always post back in the same format as srcformat.

My 2 cents.
