    <p>Here's a quick example I made up. This is the concept LukLed was talking about with calling SaveFile but don't return file contents via ajax and instead redirect to the download.</p> <p>Here's the view code:</p> <pre><code>&lt;script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(function() { // hide form code here // upload to server $('#btnUpload').click(function() { $.ajax({ type: 'POST', dataType: 'json', url: '&lt;%= Url.Action("SaveFile", "Home") %&gt;', success: function(fileId) { window.location = '&lt;%= Url.Action("DownloadFile", "Home") %&gt;?fileId=' + fileId; }, error: function() { alert('An error occurred uploading data.'); } }); }); }); &lt;/script&gt; &lt;% using (Html.BeginForm()) { %&gt; &lt;div&gt;Field 1: &lt;%= Html.TextBox("field1") %&gt;&lt;/div&gt; &lt;div&gt;Field 2: &lt;%= Html.TextBox("field2") %&gt;&lt;/div&gt; &lt;div&gt;Field 3: &lt;%= Html.TextBox("field3") %&gt;&lt;/div&gt; &lt;button id="btnUpload" type="button"&gt;Upload&lt;/button&gt; &lt;% } %&gt; </code></pre> <p>Here's the controller code:</p> <pre><code>[HandleError] public class HomeController : Controller { public ActionResult Index() { return View(); } public JsonResult SaveFile(string field1, string field2, string field3) { // save the data to the database or where ever int savedFileId = 1; // return the saved file id to the browser return Json(savedFileId); } public FileContentResult DownloadFile(int fileId) { // load file content from db or file system string fileContents = "field1,field2,field3"; // convert to byte array // use a different encoding if needed var encoding = new System.Text.ASCIIEncoding(); byte[] returnContent = encoding.GetBytes(fileContents); return File(returnContent, "application/CSV", "test.csv"); } public ActionResult About() { return View(); } } </code></pre>

    1. CONate, thanks for providing such a detailed example. I appreciate it and also thanks LukLed for trying diligently to explain your solution. The point that wasn't sinking-in was that the first call prepared the data to be saved, and 2nd call does the download.

Querying!

 
Guidance
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).
