    <p>This function is wired up to the click event of a button:</p> <pre><code>function BlahBlahBlahWCFXML() { varType = "POST"; varUrl = "http://123.123.123.123/NameOfService.svc/GetStuffById"; varData = '{"stuffId": "' + 12345678-abcd-9012-3456-abcdefghjkl' + '"}'; varContentType = "application/json; charset=utf-8"; varDataType = "xml"; varProcessData = true; CallService(); } </code></pre> <p>That function then calls this one:</p> <pre><code>//Generic function to call AXMX/WCF Service function CallService() { $.ajax({ type : varType, //GET or POST or PUT or DELETE verb url : varUrl, // Location of the service cache : false, data : varData, //Data sent to server contentType : varContentType, // content type sent to server dataType : varDataType, //Expected data format from server processdata : varProcessData, //True or False success : function(msg) {//On Successfull service call ServiceSucceeded(msg); }, error: ServiceFailed// When Service call fails }); } </code></pre> <p>When I try to run the sample, I get the following in Google Chrome's developer tools, console window:</p> <p>Failed to load resource: the server responded with a status of 400 (Bad Request) XMLHttpRequest cannot load <a href="http://123.123.123.123/NameOfService.svc/GetStuffById" rel="nofollow">http://123.123.123.123/NameOfService.svc/GetStuffById</a>. Origin null is not allowed by Access-Control-Allow-Origin.</p> <p>The service is working fine and I'm currently calling it from webforms and console apps. GetStuffById is the method I want to call. It accepts a string (GUID in this case) as a parameter and returns a string.</p> <p>The service is a WCF service and is configured to return a SOAP message. I'd prefer JSON but that's another issue for another question some other day.</p> <p>Any ideas what's going on here? Thanks!</p> <p>UPDATE #1 - I changed the POST to a GET. Still no-go.</p>

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).
