HttpPostedFileBase always remaining null mvc

Question

i know that there is a lot of questions like this, but i read them all and null of them solved my problem. Here below im going to show the code that i have in my view and my controller so that you can have an idea of my code.

View :
<td><% using (Html.BeginForm("Index", "Home", FormMethod.Post, new {enctype = "multipart/form-data"})) { %>
<%: Html.ValidationSummary(true) %>
                <div id="section1"> 
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Name) %>
    </div>
<label for="file">Filename:</label>
        <input type="file" name="myfile" id="File5" value="Choose File Banner1" />
     <p>&nbsp;</p>

And here is my controller:
[AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(HomeModel model, string submitButton, HttpPostedFileBase myfile)
    {

I cant figure out what mite be the problem.. can someone help me please

everything looks fine to me.. just to make sure, you don't have anyother field in the name `myfile` other than the file control right ? — AthibaN, Oct 17 '13 at 08:19
could it be there is something wrong somewhere else that is inflicting in some way ?? — user2191421, Oct 17 '13 at 09:55
not sure, try the same from beginning, or do some sample application with the upload alone, make sure it works before proceeding. — AthibaN, Oct 17 '13 at 10:04
i have another application with the same code above and works good.. thats why i thinks the problem is coming from somewhere else .. — user2191421, Oct 17 '13 at 10:54

I also had the same problem and I ended up here while looking for an answer. I had forgotten the enctype parameter in the form definition

@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
// form
}

I had the same problem before, I had to remove the value from the file input to make it work :

<input type="file" name="myfile" id="File5" />

There are a number of causes for this issue:

You didn't specify the enctype attribute on the <form> tag
You didn't give a name attribute to your <input type="file"> tag
You nested a <form> tag in another <form>

If none of these are your issue, this is what worked for me: add an HttpPostedFileBase property to your view model (or create a view model with that property).

View Model

public class MyViewModel
{
    public HttpPostedFileBase MyFile { get; set; }
}

Controller

public ActionResult Index()
{
    return View(new MyViewModel());
}

[HttpPost]
public ActionResult Index(MyViewModel viewModel)
{
    HttpPostedFileBase file = viewModel.MyFile;

    if (file != null && file.ContentLength > 0)
    {
        // Your code here
    }
}

Try using html attribute "@data_ajax = "false" " in the view, near the enctype

(Html.BeginForm("Index", "Home", FormMethod.Post, new {enctype = "multipart/form-data", @data_ajax = "false" }))

Could it be that you have a value="" set in the input element?

I copied a UI into my working MVC3 application and found upload part starts giving same error. I found out there was an extra form (making it a nested form) in Page Layout. I removed it and everything worked fine for me.
