I am using Razor, c# and Jquery to attempt to upload a file - along with the form data.

Currently I have this:
@using (Html.BeginForm("MyAction", "MyController", FormMethod.Post, new { enctype = "multipart/form-data", id = "uploadForm" }))
<input id="fileupload" type="file" name="attachmentFile" required />
<input type="hidden" name="Id" value="@Model.Id" />
<ul>
                @foreach (var location in Model.testLocation)
                {
                    <li><label><input type="radio" name="testLocation" required value="@location.Value" @(location.Selected ? "checked='checked'" : "") />@location.Text</label></li>
                }
            </ul>
<button type="submit" class="btn">Upload</button>

Open in new window


No I am trying to use this AJAX to upload the file asynchronously.

$("form#uploadForm").submit(function () {
        var testLocation = $("input:radio[name='testLocation']:checked").val();
        $.ajax({
            url: "@Html.Raw(Url.Action("MyAction", "MyController", new { Id = Model.Id, testLocation = "abc" }))".replace("abc", testLocation),
            type: 'POST',
            async: false,
            success: function (data) {
                $('#errors').text(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });

        return false;
    });

Open in new window



And my controller looks like this:

[HttpPost]
	    public ActionResult MyAction(int Id, HttpPostedFileBase attachmentFile, TestLocation testLocation)
	    {
            //do some stuff and return errors.
	    }

Open in new window


However, my attachmentFile is always null?

Since attachmentFile is not in url so it doesn't map to it.

To get your attachment use Request object. Inside your action use below code.

HttpPostedFileBase myFile = Request.Files["fileupload"];

You are not submitting the form with $.ajax therefore the file is not even uploaded to the server. There is no other HTML only way to upload a file from the client side except through submitting the form. In HTML5, however, the new XMLHTppRequest2 object has some new API that allows async/ajax upload of files (http://www.sitepoint.com/html5-ajax-file-upload/)

That said, since you are using jQuery you should be able to find a plugin for ajax upload that gracefully regresses and uses the best available method for uploading a file async.

Hi. Thanks I have found the Ajax form plugin which seems to do exactly that.
