    <p>I'm trying to upload a file with ajax, jquery and formdata without doing a refresh. Unfortunately, when i am trying to read the file in my controller it says that the file is empty and i have no idea why.</p> <p>The div "uploadForm" is the form itself.</p> <p>JQuery:</p> <pre><code> $("#submitImage").click(function (event) { event.preventDefault(); $('#uploadImage #submitImage').val('Uploading File..'); var formData = new FormData($('#uploadForm')); $.ajax({ url: "Upload", data: formData, processData: false, contentType: false, type: 'POST', success: function (data) { alert(data); } }); }); </code></pre> <p>Html:</p> <pre><code> @using (Html.BeginForm("Index", "Upload", FormMethod.Post, new { enctype = "multipart/form-data", @id="uploadForm"})) { &lt;input type="submit" value="Upload Image" id="submitImage"/&gt; &lt;input type="file" name="file" id="bannerImage" value="Choose file" /&gt; } </code></pre> <p>Controller:</p> <pre><code> [AcceptVerbs(HttpVerbs.Post)] [HttpPost] public ActionResult Index(HttpPostedFileBase file) { Functions Functions = new Functions(); string Filename = Functions.GenerateUniqueFileName(); if (file == null) { ViewBag.Test = "Ajax call complete, but the file is empty"; } else { ViewBag.Test = "Ajax call complete, and the file isn't empty!"; } return View(); } } </code></pre> <p>Live demo: <a href="http://upload.jamieknoef.nl/" rel="nofollow">http://upload.jamieknoef.nl/</a> (You only need to use the choose file &amp; upload file buttons)</p> <p><strong>Edit: Fixed, see my other post for the answer!</strong></p> <p>Thanks in advance!</p>

    1. COwhy dont you try passing the data in ajax call in json format like this. `var fileName=$('#bannerImage').val(); $.ajax({ data:{flName:fileName } } );`

    2. COI don't know what that "FormData" thing is, but you can't upload files via plain jQuery `$.ajax()` like that.

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.
