It seems to me that you posted the issue in the wrong forum. It can be that you have WCF or MVC problem. In the case you can post you question on http://stackoverflow.com/ for example.

If you use commertial version of jqGrid and thy think that your problem is really connected with jqGrid you should post the description of the problem in http://www.trirand.net/forum/.

Here is the forum for open source JavaScript version of jqGrid.

Specificially i'm using a WCF Service to fetch my IQueryable<T> and then I'm simply attempting to bind it.

The error I'm getting is "object null" and its being thrown from with in the triand assembly. 

   at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation)   at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a()   at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters)   at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters)   at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters)   at lambda_method(Closure , ControllerBase , Object[] )   at ABC.WONK.Admin.Controllers.OrganizationsController.SearchGridDataRequested() in C:\Source\kss\regportal\portal.admin\Controllers\NiftyController.cs:line 172   at Trirand.Web.Mvc.JQGrid.DataBind(Object dataSource)   at Trirand.Web.Mvc.JQGrid.DataBind()   at Trirand.Web.Mvc.JQGrid.GetJsonResponse()   at Trirand.Web.Mvc.JQGrid.FilterDataSource(Object dataSource, NameValueCollection queryString, IQueryable& iqueryable)   at Trirand.Web.Mvc.Util.ConvertToJson(JsonResponse response, JQGrid grid, DataTable dt)at Trirand.Web.Mvc.Util.PrepareJsonResponse(JsonResponse response, JQGrid grid, DataTable dt)

Possible null value passed in the IQueryable<T> result set?  I looked and when I was looking at the data it was no null values.

Could this be a timing thing?  I was thinking perhaps my WCF results were comming back to late...but that would have to be a very rapid timeout on the controls part.  It happended with in 2 seconds of page creation.
