I have implemented Jqgrid in a Sharepoint visual webpart using the approach documented in this article http://www.mindsharp.com/blog/2012/05/integrating-jqgrid-with-sharepoint-quickstart/ It' works great on my local Sharepoint 2010 server. I deploy the webpart to another Sharepoint 2010 server and I am getting the error listed at the bottom of my question.
How can I be seeing this error about method Count not being supported? It is the same version of Sharepoint and the same code.
