download file with DirectEvent on GridPanel

How is it possible to download a file with a directEvent on a node in a GridPanel. I pass the path of the file to the controller:

Code:

---

.DirectEvents(de =>
                                {
                                    de.Select.Url = "/FolderData/DownloadFile";
                                    de.Select.Method = HttpMethod.GET;
                                    de.Select.ExtraParams.Add(new Parameter("data", "record.get('path')", ParameterMode.Raw));
                                })

---

Code:

---

public FileResult DownloadFile(string data)
        {
            string contentType = getMimeType(data); // here is mime type

            return new FilePathResult(data, contentType);
        }

---

i receive Bad response illegal character .

forgott isUpload = true, can be closed.
