ok, I\'m back. I totally simplified my problem to just three simple fields and I\'m still stuck on the same line using the addJSONData method. I\'ve been stuck on this for d
WebForm is dying out, so we need to focus on latest technologies like asp.net MVC. I have found a new asp.net jQGrid integration here http://www.techdoubts.net/2017/05/full-integration-dynamic-jqgrid-asp-net-mvc.html
Since we got a lot of questions for ASP.NET WebForms and jqGrid, we decided to go the "component" way and implement something that is very similar to asp:GridView. This way, you can control jqGrid using the familiar ASP.NET page lifecycle, events, datasources, etc.
You can see a Beta of this online here - more than 30 samples available currently:

It will most probably grow into commercial product as well (open source licenses will be available) if there is interest in that. Meanwhile, you can use Reflector to check out the sources for reference (until we figure out a way to have the source available online). We are using SVN for ASP.NET as opposed to gitHub for the js Core, so we have some work in that direction.
We hope this helps the community.
