In my Controller I have a GenerateDocument method that returns a FileStreamResult. In my view I have javascript that simply opens a new like so; window.open('/controller/GenerateDocument/?id=blah'); I need my GenerateDocument method to: 1. return a pdf when the document can be created/fetched without errors, 2. return a new page/view when there are errors. Here's the Controller code: <pre><code> public FileStreamResult GenerateDocument(int id) { string errorResult = string.Empty; try { DocumentDetail documentDetail = DocumentGenerator.GenerateAgreements(id, DcmDocumentEntityType.Sponsor, GetAuthUser()); if (documentDetail == null) return null; Stream stream = DocumentGenerator.RetrieveFile(documentDetail); return new FileStreamResult(stream, "application/pdf"); } catch (Exception ex) { errorResult = FormatException(ex); Trace.TraceError(errorResult); } //ViewBag.Error = HttpUtility.HtmlEncode(errorResult).Replace("\n", " "); //return View("DocGenerationError"); return null; } </code></pre> I tried using using ActionResult and returning the view in case of an error, but as I noted in a comment on this thread, in the page javascript, window.open(url) would not work right. Here's the view code: <pre><code> $('#ActionMenu').change(function() { var action = $(this).val(); switch (action) { case 'Generate Sponsor Agreement': window.open('/Sponsor/GenerateDocument/?id=@(Model.SponsorID)'); break; other cases default: } }); </code></pre> Note: the Controller code above WORKS. It's when I switch to returning an ActionResult and uncomment out the exception handling stuff that it stops working.

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.
