I am working to an application that uses jqGrid. The problem is that the edit dialog that should appear at row edit must have a specific layout. So I would prefer to load it via
You can check this Tutorial, which is the official demo website of jqGrid Plugin. I am sure that there are examples of some "Row Editing" in that category. You can view lots of other examples of jqGrid also, in this demo website.
You can also check the Home page.
If you have any more problems, you can ask it here. I did use some of those examples in one of my client's (confidential) website, so it will be easy to manipulate according to your needs.
Hope it helps.
