    <p>Here's my client-side code:</p> <pre><code>$("#grid").jqGrid({ url: "/Entry/EntryListingByBreed/", datatype: "json", mtype: "POST", postData: { showId: showId, breedId: breedId }, colNames: ["Class", "NZKC Reg", "Registered name", "Date of birth", "Entered"], colModel: [ { name: "ClassNumber", sortable: false, width: 50 }, { name: "NZKCRegistration", sortable: false, width: 100 }, { name: "RegisteredName", sortable: false, width: 200 }, { name: "DateOfBirth", sortable: false, width: 200 }, { name: "Entered", sortable: false, width: 200 } ], pager: jQuery("#pager"), rowNum: 20, rowList: [10, 20, 40], altRows: true, altclass: "gridAltRow", viewrecords: true, caption: "Entries for " + breedName }); </code></pre> <p>and here is my server-side code:</p> <pre><code> [RequiresAuthentication] [HttpPost] public ActionResult EntryListingByBreed(int showId, int breedId, string sidx, string sord, int page, int rows) { using (var dataContext = new NZDogShowsEntities()) { int pageIndex = page - 1; int pageSize = rows; var entries = from se in dataContext.ShowEntries where se.ShowID == showId &amp;&amp; se.Entry.BreedID == breedId select se; int totalRecords = entries.Count(); int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize); var showEntries = (from se in dataContext.ShowEntries.AsEntryListingAggregate().AsEnumerable() where se.ShowID == showId &amp;&amp; se.Entry.BreedID == breedId select new { ID = se.ID, ClassNumber = se.Class.Number.ToString(), NZKCRegistration = se.Entry.NZKCRegNumber, RegisteredName = se.Entry.RegisteredName, DateOfBirth = se.Entry.DateOfBirth.GetValueOrDefault().ToLongDateString(), Entered = se.Entry.DateOfBirth.GetValueOrDefault().ToLongDateString() }).ToList(); var jsonData = new { total = totalPages, page = page, records = totalRecords, rows = ( from entry in showEntries select new { i = entry.ID, cell = new string[]{ entry.ClassNumber, entry.NZKCRegistration, entry.RegisteredName, entry.DateOfBirth, entry.Entered } }).ToArray() }; var viewData = Json(jsonData); return viewData; } } } </code></pre> <p>My server-side code looks a bit more verbose than necessary but it was good while I'm troubleshooting. The <code>viewData</code> variable is showing all the right data, number of rows, page number, etc. etc.</p> <p>The grid is formatted, ie. showing all the chrome surround, etc. However, no data is shown. Even the "Page x of y" is not correct. It's showing "Page 0 of" and the <code>&lt;span&gt;</code> where total number of records should show is blank. I'm at a lost here - probably missing something terribly obvious, especially since I'm a newbie to all this.</p> <p>Any help/pointers (pun-intended) would be greatly appreciated.</p> <p>Thanks.</p> <p>EDIT: Ok, the above server-side code has been fixed and now produces JSON string. It appears to be correctly formatted. I won't update the above code but will provide the JSON string below. It parses correctly but still Firebug reports "invalid label". The grid is not being populated either! Here's the string - can't for the life of me spot the problem:</p> <pre><code>{"total":2,"page":1,"records":25,"rows":[{"id":2,"cell":["2a","1234567","Test Dog","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":3,"cell":["4a","abcdef","Test Dog 2","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":4,"cell":["5a","abc123","Test Dog 3","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":5,"cell":["6a","asdf890","Test Dog X","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":6,"cell":["6","qwerty","Test Dog Y","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":7,"cell":["1","fw3asd","Test Dog 4","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":8,"cell":["10","asdfa","Test Dog 5","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":9,"cell":["11a","houh2","Test Dog 6","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":11,"cell":["8","xxxx","Test X","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":12,"cell":["8","zzzz","Test Z","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":13,"cell":["1","qqqq","Test Q","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":14,"cell":["8a","tttt","Test T","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":15,"cell":["8a","rrrr","Test R","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":16,"cell":["7","aaaa","Test A","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":17,"cell":["1","11223344","Test Entry","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":18,"cell":["1","66778899","asdfa","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":19,"cell":["1","13o24bo","qwlen;oq","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":20,"cell":["1","oubiou","asdfa","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":21,"cell":["1","o2no3","hohohop","Monday, 1 January 0001","Monday, 1 January 0001"]},{"id":22,"cell":["1","o48t2","Test 09808","Monday, 1 January 0001","Monday, 1 January 0001"]}]} </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.
