Async Upload with additional fields

[OnaBai]

I'm trying to upload a file to a document in CouchDB.
To do so, I need to provide the document identifier as part of the url AND a revision as an additional field. This is not a problem if I'm submitting a form with both inputs (revision and file) but I wonder if it is possible with asynchronous upload do something similar. Is it? How?

Hi Emiliano,

Unfortunately the Upload does not support the described behavior, i.e. it cannot send additional data to the server. You should use the widget's events and post the other fields manually.

I'm not exactly sure what you're asking, but I am sending two drop down values with my async upload by attaching them to the saveUrl.

$("#files").kendoUpload({

    async: {

        saveUrl: "save",

        autoUpload: true

    },

    upload: function (e) {

        e.sender.options.async.saveUrl = "save?t=" + $("#t").val() + "&q=" + $("#q").val();

    }

});

$("#files").data("kendoUpload").options.async.saveUrl = "save?t=" + $("#t").val() + "&q=" + $("#q").val();

Something like that.

The same works quite well using Razor:

@(Html.Kendo().Upload()

 .Name("files")

 .Async(a => a.Save("Save", "Media", new { dir = "bla" })

  .Remove("Remove", "Media")

  .AutoUpload(false))

)

and here's the controller:

public ActionResult Save(IEnumerable<HttpPostedFileBase> files, string dir)
