    <p>I have a form which can contain files and it shows a progress bar successfully. My problem is that in the MVC Controller I have:</p> <pre><code>return RedirectToAction("Complete", new { title = title }); </code></pre> <p>This goes and executes the Complete method if I step through but it then goes back to the JavaScript load event and does not redirect me unless I add a JavaScript redirect in the load event listener (uploadComplete):</p> <pre><code>var xhr = new XMLHttpRequest(); xhr.upload.addEventListener("progress", uploadProgress, false); xhr.addEventListener("load", uploadComplete, false); xhr.addEventListener("error", uploadFailed, false); xhr.addEventListener("abort", uploadCanceled, false); xhr.open("POST", "/Submit-Recipe", true); xhr.send(fd); function uploadComplete(evt) { //var valueFromController = how do I get a value here?; //window.location.replace("http://@ConfigurationManager.AppSettings["website"]/SubmitRecipeComplete/" + valueFromTheController); } </code></pre> <p>Is there a way to not have to add a JavaScript redirect? If I do need a JavaScript redirect, how can I pass a variable back from the controller when it needs to be an ActionResult (for if there is an error and I need to redisplay the page?).</p> <p>I can work around this by adding a second page where I could know the "valueFromController" but 2 forms breaks the workflow a bit.</p> <p><strong>EDIT</strong></p> <p>I did what Praveen said but GetData() did not work for me so I used this instead:</p> <pre><code>evt.currentTarget.responseText </code></pre> <p>To determine if to return the View or Content I added this just before xhr.send(fd);</p> <pre><code>xhr.setRequestHeader('X-Requested-With', 'XMLHttpRequest'); </code></pre> <p>In the controller I can then do:</p> <pre><code>if (Request.IsAjaxRequest()) { return Content(title); } </code></pre>

    1. CORedirectToAction is only used by the controller, it does not return a redirect to the web browser, ie HTTP 302 or HTTP 301

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.

SQuiL has stopped working due to an internal error.

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