Ha ha, just figured that out 10 mins ago, I thought the docs said subGridType.

Thanks

Matt

Sorry for this error in the documentation. All the defined properties which contain datatype are in lower cases.

Just replace

subGridType: Function.createDelegate(this, this._FetchTravellerDetails),

with

subgridtype: Function.createDelegate(this, this._FetchTravellerDetails),

Corrected in the docs.

Thank you very much

Best Regards

Tony

Have been working with jGrid for a week now and have got a basic grid with paging and sorting working fine. I've now been asked to add a subgrid to show extended details of each row and my solution isn't work. The grid loads fine and show the data, but when I click on the '+' next to each row, the loading div is shown and the grid data disappears. Behind the scenes the function _FetchTravellers is called for the subgrid instead of _FetchTravellersDetails.

Am I doing something really wrong? Please excuse any stupidity as I'm a .Net developer and have been working with jQuery and this grid for just over a week now! Please let me know if more information is required.

I'm using ASP.NET and WCF to get the data.

jGrid 3.5.3

Here's my code for the grid:

$('#grid').jqGrid({
                datatype: Function.createDelegate(this, this._FetchTravellers),
                colNames: ['Code', 'FirstName', 'Surname', 'Email', 'Office', '', ''],
                colModel: [
                    { name: 'code', index: 'code', key: true, search: false, hidden: true },
                    { name: 'firstname', index: 'firstname', sorttype: 'text' },
                    { name: 'surname', index: 'surname', sorttype: 'text' },
                    { name: 'email', index: 'email', sorttype: 'text', width: 120 },
                    { name: 'office', index: 'office', sorttype: 'text', width: 70 },
                    { name: 'edit', index: 'edit', align: 'center', search: false, sortable: false, width: 55 },
                    { name: 'remove', index: 'remove', align: 'center', search: false, sortable: false, width: 80}],
                rowNum: 20,
                rowList: [10, 20, 30],
                viewrecords: true,
                pager: $('#grid'),
                height: 300,
                width: 550,
                jsonReader: {
                    root: "rows",
                    page: "page",
                    total: "total",

                    id: "code",
                    subgrid: { root: 'rows', repeatitems: false }

            var jdata = JSON.parse(ajaxData.d);
            thegrid.addJSONData(jdata);

            var ids = $('#' + this._dataTableID).getDataIDs();
            for (var i = 0; i < ids.length; i++) {
                var ft = ids[i];
                editLink = "<a href=\\"../FrequentTraveller/TravellerDetails.aspx?id=" + ft + "\\">edit</a>";
