How to fire Upload in a form submit and pass HttpPostedFileBase to server-side?

[John]

How can I implement firing upload while clicking submit as below code?

@using (Ajax.BeginForm("Upload", null, null, null }))

{

<input id="Uploaded" name="Uploaded" type="file" />

<input type="submit" class="buttonPro k-upload-selected" value="Add"  />

}

for server-side, code is :

[HttpPost]

public Boolean Upload(HttpPostedFileBase Uploaded)

{

  ...

}
