I am facing a similar issue, after I upgraded from 3.7 to 4.2.

I have 2 rows selected in the grid, and both checkboxes are also shown checked.

But when I uncheck one checkbox to deselect it, other checkbox also gets unchecked, althouth the other item shows selected(highlighted – css).

This is really wierd and I am not able to crack it.

Anyone has any idea?

I am using JqGrid with MVC using Json format. I am able to display data in jqgrid successfully. sorting, paging, filtering etc works fine too.

Issue: While selecting a row, the selection is not working properly, if I make the unique row id in the Json format as "String". if I select one row, some other row is getting selected. Also if I select the check box in the top ("selectAll/Multi select checkbox), rows are getting highlighted but check boxes for individual rows are not getting selected.

Question: do we need to make the unique row id in the JsonFormat as Integer like 1,2,3 etc??? Is it mandaory???

If I make the unique row id in the Json format as "Integer", this selection works fine.

Here is my code. controller, view, repository with hard coded data.

-------------------------------------------------------------------------------------------------------------
My Controller action:

 public virtual JsonResult GetJQGridJsonData(int page, int rows, string search, string sidx, string sord)
        {

            List<Product> jqData = new List<Product>();
            jqData = Repository.GetProducts();
           
            int pageSize = rows;
            int totalRecords = jqData.Count();

            int totalPages;
            if (totalRecords > 0)
                totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
            else
                totalPages = 0;

            var jsonData = new JqGridJsonData
            {

                total = totalPages,
                page = page,
                records = totalRecords,

                rows = jqData.Select(vm =>
                             new JQGridRowJson
                             {
                                 id = vm.ProductId.ToString(),
                                 cell = new[]{

                                                   vm.ProductId.ToString(),
                                                   vm.ProductNumber,
                                                   vm.Size,
                                                   vm.ReleaseDate.ToShortDateString(),
                                                   vm.Amount.ToString(),
                                                   vm.Description
                                }
                             }).ToArray()

            };
            return Json(jsonData, JsonRequestBehavior.AllowGet);
        }
