Hi,

  IN MY VIEW,

@using (Html.BeginForm("InsuranceInformation", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
    {  
            <div>
            <input type="file" name="file" id="file" />
             <input type="submit" value="submit" />
           </div>
    }

And in my Home controller ,
public void InsuranceInformation(HttpPostedFileBase file)
        {
            if (Request != null)
            {                
                foreach (string files in Request.Files)
                {
                    HttpPostedFileBase hpf = Request.Files[files];
                    //Save file here
                }
            }
        }

NOW I am uploading a file but after submitting , in controller I am getting file as null
 Could you please say me what is wrong in it. And I am using asp.net mvc

You need to use the HttpPostedFileBase that you pass to the method rather than request.files collection.
public void InsuranceInformation(HttpPostedFileBase file)
{
    if (file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/Path to save to"), fileName);
        file.SaveAs(path);
    }
}

Have you decorated the controller method with a [HttpPost] attribute?

Well, on the face of it everything looks ok. Try this simplified version and see if you get an object reference:
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <div>
        @using (Html.BeginForm("InsuranceInformation", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
        {
            <input type="file" id="file" name="file" />
            <input type="submit" />
        }
    </div>
</body>
</html>

Open in new window

And in the Home controller:
[HttpPost]
public ActionResult InsuranceUpload(HttpPostedFileBase file)
{
     return View();
}

Open in new window

Put a breakpoint at the start of the method and see if file contains anything when posted back.

Hi

I solved this problem, it is basically inheriting the layout page , this layout is jquery mobile page so either i have to add layout =null or i have to add

@data_ajax = "false"  to my Html.BeginForm method.

any how thanks for your response
