KendoUpload FileUpload httppostedfile not working on submit - asp.net-mvc

Question

I am using #(Html.Kendo().Upload() in my app. I have to take the top 5 records from csv and bind it to kendo grid in javascript. I'm reading the file info from httppostedfilebase and returning the top 5 records as JSON result in save action method. On Upload success in javascript i'm binding the grid.
Now on submit, i have to read the file again. i'm trying to read the file information from httppostedfilebase but it is null because the save action method returns JSON. If i change the save action method to view, i'm ablet o read the httpostedfilebase on submit.
Is there a workaround?
Thanks!

console.log(url);
$.ajax({
url: url,
type: 'POST',
data: $('form#LoadForm').serialize(),
async: false,
success: function (data) {
alert("success");
},
error: function (data, xhr, error) {
alert("error");
}
});
}
onSuccess(e)
{ var grid = $("#grid").data("kendoGrid");
var origData = e.response;
grid.dataSource.data(origData);
}
document ready
--------------
var grid = $("#grid").kendoGrid({
groupable: false,
scrollable: true,
columnMenu: true
}).data("kendoGrid");
code behind
-----------
public JsonResult UploadData(IEnumerable<HttpPostedFileBase> uploadTemplate, FileModel fileModel)
{
Stream inputFileStream = new MemoryStream();
string[] result = new string[] { };
if (uploadOnly)
{
if (uploadTemplate != null)
{
try
{
foreach (var file in uploadTemplate)
{
inputFileStream = file.InputStream;
}
// GET TOP N ROWS AND ASSIGN TO parentRow
return Json(parentRow, JsonRequestBehavior.AllowGet);
}
return null;
}
public ActionResult fileSubmit(IEnumerable<HttpPostedFileBase> uploadTemplate, FileModel fileModel)
{
//retrieve uploadTemplate here (no values in uploadTemplate.)
}
