Question

i want upload a XML file in jquery popup with out page refresh

Answer 1

Actually it’s easy for the client side, a simple ajax call will do the work on the headers

<form enctype="multipart/form-data" method="post" name="fileinfo">
    <input type="file" name="file" required />
</form>

var data = new FormData();
data.append('element',$(this)[0].files[0])
$.ajax(
{ 
    url : 'Your controller action',
    data: data,
    cache: false,
    contentType: false,
    processData: false,
})

Server side it’s a action and you can recieve this value

public ActionResult UploadXml(HttpPostedFileBase dataXml)
{
    dataXml.SaveAs("string with the path");
    return View();
}

This is not suppored by IE only for webkit ff and IE from 10
