ASP.NET MVC2, can I use a model field as an html id? - asp.net-mvc

Question

I am a newbie in ASP.NET and html.
I want to upload a file, so I have a model with a HttpPostedFileBase field, and a strongly-typed view that gets the model in order to get the value of the file.
My question is, how can I send to the controller the value of the file?
This is my html code, I'd like to send the value of File to Model.File, but placing <%:Model.File:> instead of file1 does not work :(
<label for="file1">File: </label>
<input type="file" name="file1" id="file1" size="40">
P.S.: I've also tried using the asp:FileUpload but I don't what how to send the result to the controller.
EDIT:
Ok, I go for posting my code, thank you very much ZeNo.
Here is the Model:
public class AddProductModel
{
[...]
public HttpPostedFileBase File { get; set; }
}
This is my View:
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Application.Models.AddProductModel>" %>
<form id="form1" runat="server">
<% using (Html.BeginForm()) { %>
<% Html.EnableClientValidation(); %>
<fieldset>
[...]
<div>
<label for="file1">File: </label>
<input type="file" name="file1" id="<%: Model.File %>" size="40">
<br />
</div>
<br />
<p>
<input type="submit" value="Add!" />
</p>
</fieldset>
<% } %>
</form>
Here is my controller, I use the debugger here and it says that model.File is empty:
[HttpPost]
public ActionResult AddProduct(AddProductModel model)
{
if (model.ProductName != null && model.ProductDescription != null)
objRepository.addToProducts(model);
return RedirectToAction("/AddProduct");
}

Answer 1

Use <%:Model.File %> instead.

Answer 2

put you file control inside a form tag
<form action="/Home/GetFile" id="myform">
<input type="file1" id="file1"/>
</form>
<script type="text/javascript" language="javascript">
var form = $("#myform");
form .submit();
</script>
controller:
[HttpPost]
public ActionResult GetFile(HttpPostedFileBase file) {
if (file.ContentLength > 0) {
var fileName = Path.GetFileName(file.FileName);
}
}

Answer 3

Change your view to:
<form action ="/AddProduct" id="myform">
<% Html.EnableClientValidation(); %>
<fieldset>
<div>
<label for="file1">File: </label>
<input type="file" name="file1" id="<%: Model.File %>" size="40">
<br />
</div>
<br />
<p>
<input type="submit" value="Add!" />
</p>
</fieldset>
</form>
notice I have removed form runat="server".. also there were nested forms..
add this Javascript snippet:
<script type="text/javascript" language="javascript">
var form = $("#myform");
form .submit();
</script>
in the controller make following changes:
[HttpPost]
public ActionResult AddProduct(HttpPostedFileBase file)
{
if (file.ContentLength > 0) {
var fileName = Path.GetFileName(file.FileName);
}
return RedirectToAction("/AddProduct");
}
