Once again, thanks very much indeed for your help.
I have set the MIME type in IIS to application/JSON, and have included a tag into my ColdFusion CFC to make absolutely certain that it is sending JSON.
the JSON data which you posted in your first question and which I used in my answer (and my demo too) was correct JSON data. The ROWS property was array of arrays ({“ROWS”:“1”,…],[“2”, …, …).
You are right, there are a mistake in the documentation of jqGrid. Fortunately the documentation is wiki-documentation and everybody can change it. So I fixed the corresponding place in the documentation just now.
