    <p>I am new to jqGrid and I have found it difficult to follow the documentation <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki%3ajqgriddocs" rel="nofollow">jqGrid Documentation</a></p> <p>I cannot figure out how to call a WebMethod when setting up the JQGrid. I have been successful in making an Ajax call to get the data and then setting up the JQGrid with local data. I think its an extra step in the setup process and that I should be able to provide the path to the webmethod using the url property.</p> <p>The editurl property is the same way. I am never actually receiving the post to the server.</p> <p><strong>Original Code</strong></p> <p><strong>Attempted JQGrid Setup</strong></p> <pre><code> function GetData() { $('#list').jqGrid({ type: "POST", url: "Default.aspx/GetUsersJSON", datatype: "json", height: 250, colName: ['Username', 'Email'], colModel: [ ... }).jqGrid( 'navGrid', '#pager', { edit: true, add: true, del: true }); } </code></pre> <p><strong>WebMethod</strong></p> <pre><code> [WebMethod] public static string GetUsersJSON() { var users = new List(); using(UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext()) { users = uasd.GetUserList(); } JavaScriptSerializer serializer = new JavaScriptSerializer(); return serializer.Serialize(users); } </code></pre> <p><strong>Current Code</strong></p> <p>I got it working correctly now, but I still have one final question. Why did I have to set the 'repeatitems: false' in order to display the content?</p> <p>Some of the caveats to get this to work include the different ways to setup the ajax request.</p> <p>(Ajax: type) is (jqgrid : mtype) (Ajax: contentType) is (jqgrid : ajaxGridOptions: { contentType: })</p> <p>And finally understanding the documentation from the documentation on how to setup the JSONReader.</p> <p>Hope this helps others and thanks Oleg for all your help.</p> <p><strong>JS</strong></p> <pre><code> function GetUserDataFromServer() { $('#list').jqGrid({ url: "Default.aspx/GetUsersJSON", mtype: 'POST', ajaxGridOptions: { contentType: "application/json" }, datatype: "json", serializeGridData: function (postData) { return JSON.stringify(postData); }, jsonReader: { root: function (obj) { return obj.d; }, page: function (obj) { return 1; }, total: function (obj) { return 1; }, records: function (obj) { return obj.d.length; }, id:'0', cell:'', repeatitems: false }, datatype: "json", height: 250, colName: ['Username', 'Email'], colModel: [ { name: 'Username', index: 'Username', width: 100, editable: true }, { name: 'Email', index: 'Email', width: 220, editable: true }, { name: 'IsLockedOut', index: 'IsLockedOut', width: 100, editable: true, edittype: 'checkbox' } ], caption: "Users" }) } </code></pre> <p><strong>Web Method</strong></p> <pre><code> [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public static List GetUsersJSON() { using (UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext()) { return uasd.GetUserList(); } } </code></pre> <p><strong>One JSON Object from the List</strong></p> <pre><code> {"__type":"UserAdministrationSandbox.UserData","PKID":"00000000-0000-0000-0000-000000000001","Username":"TestUser","ApplicationName":"Test","Email":"TestUser@test.com","Comment":"TestUser","Password":"D41D8CD98F00B204E9800998ECF8427E","PasswordQuestion":"Is this a blank Password?","PasswordAnswer":null,"IsApproved":true,"LastActivityDate":"\/Date(1298869200000)\/","LastLoginDate":"\/Date(1298869200000)\/","LastPasswordChangedDate":"\/Date(1298869200000)\/","CreationDate":"\/Date(1298869200000)\/","IsOnLine":false,"IsLockedOut":false,"LastLockedOutDate":"\/Date(1298869200000)\/","FailedPasswordAttemptCount":0,"FailedPasswordAttemptWindowStart":null,"FailedPasswordAnswerAttemptCount":null,"FailedPasswordAnswerAttemptWindowStart":null} </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.
