Hi Markus:

You can do this:

editable:true, editoptions:{readonly:true}

for the field that you want to be posted but not really editable by the user.

My only concern with doing this is that the field will show up when you edit the row using form edit and it will appear to the user that it is editable but it really is not. But that's an optional workaround for you.

Thanks for this workaround… however, when I implement this, my 'user_id' field from my subgrid sent to the server is blank.
