jQuery Grid Plugin - jqGrid

Hi,

I'm trying to get a jqGrid to update programmatically with JSON retrieved data, but not having much luck.

I can get data to load fine if I choose datatype: "json" - this works and the grid displays as it should. However, if I manually load the data from the same URL and decode the JSON into an object, with the following:

            gdCustomers.jqGrid({
                url: "jqGrid.aspx?CallbackTarget=Proxy&Method=GetCustomerList",
                editurl: "jqGrid.aspx?CallbackTarget=Proxy&Method=UpdateCustomerRow",
                datatype: "clientside",
                colNames: ["Name", "Company", "Entered"],
                colModel: [
                             { name: "Name", index: "Name", width: 150, editable: true, edittype: "text" },
                             { name: "CompanyName", index: "CompanyName", width: 200, editable: true },
                             { name: "Entered", index: "Entered", width: 75, editable: true, datefmt: "MM/dd/yyyy" }
                             ],
                sortname: "Company",
                rowNum: 14,
                viewrecords: true,
                sortorder: "asc",
                caption: "Northwind Customer List",
                width: 800,
                height: 308,
                pager: "#gdCustomersPager",
                ondblClickRow: function(id) {
                    gdCustomers.restoreRow(lastSel);
                    gdCustomers.editRow(id, true);
                    lastSel = id;
                }
            }).navGrid("#gdCustomersPager");

           
            Proxy.GetCustomerList(function(custList) {
                alert(custList); // object is in right format               
                gdCustomers.addJSONData(custList);
            });

Specifically the problem is that addJSONData(custList) in this case doesn't do anything. No error, no message but the grid also doesn't receive the data.custData isn't JSON but it's an object, but according to the sample in the docs this is what is expected here I think (ie. an object instance rather than a JSON string - the name of the method is rather inaccurate if it's the former).

The only way I can get the data in under program control is by looping through the rows manually and then explicitly using addRowData.

While the latter works i can't seem to provide the necessary paging information (total pages, and total record count) to the grid so paging doesn't work properly.

How do I get jqGrid to load under program control using the same data that the direct JSON link uses?

TIA,
