    <p>I'm using TypeScript 0.8.2 and the latest JQuery 1.9 .d.ts definitions from <a href="https://github.com/borisyankov/DefinitelyTyped/tree/master/jquery" rel="nofollow noreferrer">https://github.com/borisyankov/DefinitelyTyped/tree/master/jquery</a></p> <p>To isolate the problem, I have a simple TypeScript class definition that tries to make a single $.ajax call using the .when() and .then() syntax. Here's my code:</p> <pre><code>/// &lt;reference path="../../jquery.d.ts" /&gt; module Demo { // Class export class TestDeferred { // Constructor constructor() { $.when(this.testAjaxCall()).then((data, status, jqXHR: JQueryXHR) =&gt; { alert(jqXHR.statusText); }); $.when($.ajax("test.htm")).then(() =&gt; { console.log("yay"); }); } testAjaxCall() { return $.ajax("Test.aspx"); } } } </code></pre> <p>In both of these test cases, I get a compile time error that says:</p> <p>Supplied parameters do not match any signature of call target and the red squiggly is on the first parameter of the .when() method. He's a screenshot:</p> <p><img src="https://i.stack.imgur.com/bA3nI.png" alt="TypeScript JQuery Deferred Compile Problem"></p> <p>As far as I can tell, the .when() method in the .d.ts file has an overload of .when(options: any) and the .ajax is defined to be of type JQueryXHR which implements the JQueryPromise interface.</p> <p>In theory this should work just fine as it mirrors the jQuery documentation for .when() <a href="http://api.jquery.com/jQuery.when/" rel="nofollow noreferrer">http://api.jquery.com/jQuery.when/</a></p> <pre><code>$.when( $.ajax("test.aspx") ).then(function(data, textStatus, jqXHR){ alert( jqXHR.status ); // alerts 200 }); </code></pre> <p>So what am I missing? Did I define something wrong?</p>

    2. COIsn't that the default look for the VS Dark theme in 2012? Maybe it's an add-in.

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.
