Blueimp File Upload: How to delete file? (MVC) - asp.net

Question

I'm attempting to tie Blueimp File Uploader into my MVC 5 solution. I have the uploads working as follows:
<span class="btn btn-success fileinput-button">
<i class="glyphicon glyphicon-plus"></i>
<span>Add files...</span>
<input id="fileupload" type="file" name="files[]" multiple>
</span>
<br />
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="width: 0%;">
<span class="sr-only">0% complete</span>
</div>
</div>
<br />
<div class="file_name"></div>
<br />
<div class="file_type"></div>
<br />
<div class="file_size"></div>
<!-- The container for the uploaded files -->
<div id="files" class="files"></div>
and the javascript
$(document).ready(function () {
var Url = "#Url.Content("~/Advertise/UploadFiles")";
$('#fileupload').fileupload({
dataType: 'json',
url: Url,
autoUpload: true,
done: function (e, data) {
// $('.file_name').html(data.result.name);
// $('.file_type').html(data.result.type);
// $('.file_size').html(data.result.size);
}
}).on('fileuploadadd', function (e, data) {
data.context = $('<div/>').appendTo('#files');
$.each(data.files, function (index, file) {
var node = $('<p/>')
.append('<img src="' + URL.createObjectURL(data.files[0]) + '" height="50" width="50"/>').append($('<span/>').text(file.name));
if (!index) {
node
.append('<br>')
//.append(uploadButton.clone(true).data(data));
}
node.appendTo(data.context);
});
}).on('fileuploadprocessalways', function (e, data) {
var index = data.index,
file = data.files[index],
node = $(data.context.children()[index]);
if (file.preview) {
node
.prepend('<br>')
.prepend(file.preview);
}
if (file.error) {
node
.append('<br>')
.append($('<span class="text-danger"/>').text(file.error));
}
if (index + 1 === data.files.length) {
data.context.find('button')
.text('Upload')
.prop('disabled', !!data.files.error);
}
}).on('fileuploadprogressall', function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .progress-bar').css(
'width',
progress + '%'
);
}).on('fileuploaddone', function (e, data) {
$.each(data.result.files, function (index, file) {
if (file.url) {
var link = $('<a>')
.attr('target', '_blank')
.prop('href', file.url);
$(data.context.children()[index])
.wrap(link);
} else if (file.error) {
var error = $('<span class="text-danger"/>').text(file.error);
$(data.context.children()[index])
.append('<br>')
.append(error);
}
});
}).on('fileuploadfail', function (e, data) {
$.each(data.files, function (index) {
var error = $('<span class="text-danger"/>').text('File upload failed.');
$(data.context.children()[index])
.append('<br>')
.append(error);
});
}).prop('disabled', !$.support.fileInput)
.parent().addClass($.support.fileInput ? undefined : 'disabled');
});
I've not tested a lot of the jQuery above. But I'm looking in to how I can delete an uploaded file? I could probably do it by calling a jQuery ajax post, but I think Blueimp has a native way to do it. But I can't find any documentation on it?? Any help appreciated.
