    <p>I have a jqGrid that is not correctly displaying the subgrid rows. When I load the page, the regular grid rows display fine as well as the plus sign next to each of them, but when I click the plus button to expand them, the "Loading..." message just remains and nothing happens. I don't know if it makes a difference, but I am trying to do it on client side (loadonce: true).</p> <p>Here is the code for creating the grid:</p> <pre><code>$("#Grid1").jqGrid({ // setup custom parameter names to pass to server prmNames: { search: null, nd: null, rows: "numRows", page: "page", sort: "sortField", order: "sortOrder" }, datatype: function(postdata) { $(".loading").show(); // make sure we can see loader text $.ajax({ url: 'WebServices/GetJSONData.asmx/getGridData', type: "POST", contentType: "application/json; charset=utf-8", data: JSON.stringify(postdata), dataType: "json", success: function(data, st) { if (st == "success") { var grid = $("#Grid1")[0]; grid.addJSONData(JSON.parse(data.d)); //Loadonce doesn't work, have to do its dirty work $('#Grid1').jqGrid('setGridParam', { datatype: 'local' }); //After rows are loaded, have to manually load subgrid rows var subgridData = JSON.parse(data.d).subgrid; var lista = jQuery("#Grid1").getDataIDs(); var rowData; //Iterate over each row in grid for (i = 0; i &lt; lista.length; i++) { //Get current row data rowData = jQuery("#Grid1").getRowData(lista[i]); } } }, error: function() { alert("Error with AJAX callback"); } }); }, // this is what jqGrid is looking for in json callback jsonReader: { root: "rows", page: "page", total: "totalpages", records: "totalrecords", cell: "cell", id: "id", //index of the column with the PK in it userdata: "userdata", repeatitems: true }, coNames: ['Inv No', 'Amount', 'Store', 'Notes'], colModel: [ { name: 'InvNum', index: 'InvNum', width: 200 }, { name: 'Amount', index: 'Amount', width: 55 }, { name: 'Store', index: 'Store', width: 50 }, { name: 'Notes', index: 'Notes', width: 100 } ], subGrid: true, subGridModel: [{ name: ['InvNum', 'Name', 'Qauntity'], width: [55, 200, 80], params: ['InvNum'] }], rowNum: 10, rowList: [10, 20, 50], pager: '#Div1', viewrecords: true, width: 500, height: 230, scrollOffset: 0, loadonce: true, ignoreCase: true, gridComplete: function() { $(".loading").hide(); } }).jqGrid('navGrid', '#Div1', { del: false, add: false, edit: false }, {}, {}, {}, { multipleSearch: true }); </code></pre> <p>Here the code that I am using in the webservice call to create the JSON data:</p> <pre><code> IEnumerable orders = getOrders(); IEnumerable items = getItems(); int k = 0; var jsonData = new { totalpages = totalPages, //--- number of pages page = pageIndex, //--- current page totalrecords = totalRecords, //--- total items rows = ( from row in orders select new { id = k++, cell = new string[] { row.InvNum.ToString(), row.Amount.ToString(), row.Store, row.Notes } } ).ToArray(), subgrid = ( from row in items select new { cell = new string[] { row.InvNum.ToString(), row.Name, row.Quantity.ToString() } } ).ToArray() }; result = Newtonsoft.Json.JsonConvert.SerializeObject(jsonData); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
