    <p>I've created an Web API controller in my MVC project. Whenever I try to POST to this controller, it try's to initiate a File download, and I am not sure why. It happens if I navigate to the API controller via URL or if it's done via a Form post. </p> <p>It's a very simple scenario where an File is to be uploaded via a post.</p> <p>Here is the controller code. Any ideas?</p> <pre><code>public class UploadController : ApiController { public async Task&lt;List&lt;string&gt;&gt; Post() { // Verify that this is an HTML Form file upload request if (!Request.Content.IsMimeMultipartContent("form-data")) { throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType); } // Create a stream provider for setting up output streams that saves the output under c:\tmp\uploads // If you want full control over how the stream is saved then derive from MultipartFormDataStreamProvider // and override what you need. MultipartFormDataStreamProvider streamProvider = new MultipartFormDataStreamProvider("c:\\tmp\\"); var task = await Request.Content.ReadAsMultipartAsync(streamProvider); return new List&lt;string&gt;(); } </code></pre> <p>Here is the client code:</p> <pre><code>&lt;!DOCTYPE HTML&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;HTML5 Multiple File Upload Sample&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form action="http://localhost:8080/api/upload" enctype="multipart/form-data" method="POST"&gt; What is your name? &lt;input name="submitter" size="40" type="text"&gt;&lt;br&gt; What files are you uploading? &lt;input name="data" type=file multiple&gt; &lt;br&gt; &lt;input type="submit" /&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COCould you show us how are you calling this controller action? I suspect that the problem is in your client code rather than the server.

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.
