    <p>I want to create a web method that accepts a List of custom objects (passed in via jQuery/JSON). </p> <p>When I run the website locally everything seems to work. jQuery and ASP.NET and everyone is happy. But when I put it on one of our servers it blows up. jQuery gets a 500 error after the ajax request with the response being:</p> <blockquote> <p>System.InvalidOperationException: EditCustomObjects Web Service method name is not valid.</p> </blockquote> <p>Here's the web service method:</p> <pre><code>[WebMethod] public void EditCustomObjects(int ID, List&lt;CustomObject&gt; CustomObjectList) { // Code here } </code></pre> <p>And my jQuery code (which I don't think matters, since the error seems to be happening on the web service level):</p> <pre><code>var data = JSON.stringify({ ID: id, CustomObjectList: customObjectList }); $.ajax({ type: "POST", url: "/manageobjects.asmx/EditCustomObjects", data: data, contentType: "application/json; charset=utf-8", async: false, dataType: "json", success: function(xml, ajaxStatus) { // stuff here } }); </code></pre> <p>The customObjectList is initialized like so:</p> <pre><code>var customObjectList = []; </code></pre> <p>And I add items to it like so (via a loop):</p> <pre><code>var itemObject = { ObjectTitle = objectTitle, ObjectDescription = objectDescription, ObjectValue = objectValue } customObjectList.push(itemObject); </code></pre> <p>So, am I doing anything wrong here? Is there a better way of passing an array of data from jQuery to an ASP.NET web service method? Is there a way to resolve the "Web Service method name is not valid." error?</p> <p>FYI, I am running .NET 2.0 on a Windows Server 2003 machine, and I got the code for the above from this site: <a href="http://elegantcode.com/2009/02/21/javascript-arrays-via-jquery-ajax-to-an-aspnet-webmethod/" rel="nofollow noreferrer">http://elegantcode.com/2009/02/21/javascript-arrays-via-jquery-ajax-to-an-aspnet-webmethod/</a></p> <p>EDIT: Someone requested some more info on the web service, I'd rather not provide the whole class but here is a bit more that may help:</p> <pre><code>[WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class ManageObjects : Custom.Web.UI.Services.Service { } </code></pre> <p>Bara</p>

    1. COCan you post your complete web service class? at least the method's parent scopes?

    2. COI would rather not post the whole web service, but see my edit above for a bit more info on the initialization of the web service.

    3. COStart by checking to see if the method actually **does** exist on the production server. Go to `http://mysite.com/manageobjects.asmx` and see what methods it lists.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
