Hi Muhammad,

Thank you for submitting a sample project. If you open the error console you'll see that the Upload can't find the UploadProfileImage_OnUpload event handler. The reason is that the handler is defined after the upload. Switching their places solves the problem:

<script type="text/javascript">

    function UploadProfileImage_OnUpload(e) {
    }

</script>

<%= Html.Telerik().Upload()
        .Name("attachments")
        .Async(async => async.Save("UploadProfileImage", "Home"))
        .ClientEvents(events => events.OnUpload("UploadProfileImage_OnUpload"))
%>

The other problem I spotted is that the Upload is named attachments, but you expect an 'attachment' parameter in the controller. Making them equal should solve that problem as well:

[HttpPost]
public ActionResult UploadProfileImage(HttpPostedFileBase attachments)
