Thank you for your help.  I was able to get the paging working with providing an IQueryable to the grid.  However, I now am having a problem with doing filtering.  Because of the requirements we have been given, the filtering criteria are in a partial form outside of the grid.  So I am trying to submit the filtering criteria (along with the paging information) through an AJAX call.  But when the grid renders the results, it is not showing the correct number of records (even though when I step through the code it has the correct data).  I'm not sure if I am rebinding the data correctly.  Please look at the code below and let me know if you have any suggestions.  If you could reply to me at mlipkowitz@epic-premier.com I would really appreciate it.

Thank you.

Mike

Hi Dave,

Please find the attached MVC project with igGrid. I hope it helps you see what is the issue with your project. You can pay attention how the data for the grisd implements IQueryable:

  public ActionResult Index()
  {
   return View(this.GetProducts().AsQueryable());
  }

I also suggest to have a look at the following resources:

Please let me know if you have some questions, I will be glad to help.
