Question

I came across the following issue:
I have this model

public class Region
{
    public int RegionID { get; set; }
    public string RegionName { get; set; }
    public HttpPostedFile CustomFile { get; set; }
}

and I have a custom extension html helper method from here.

Now in the view I have the following code:

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

{%>

  <%: Html.TextAreaFor(x => x.RegionID, Model.RegionID)%>
  <br />
  <%: Html.TextAreaFor(x => x.RegionName, Model.RegionName)%>
  <br />

 <%: Html.FileBoxFor(x=>x.CustomFile, Model.CustomFile) %>

<input type="submit" />

When it reaches my controller action the CustomFile field is empty, but all other fields are properly set. If I change the CustomFile property to string instead of HttpPostedFile, I get correctly the file name (“dog.jpg” for example). Is there any way to get the full HttpPostedFile file correctly?

Thanks in advance,
Tamash

Try replacing HttpPostedFile by HttpPostedFileBase in your view model:

public class Region
{
    public int RegionID { get; set; }
    public string RegionName { get; set; }
    public HttpPostedFileBase CustomFile { get; set; }
}

Also make sure that the custom FileBoxFor helper you are using generates correct name and type of the corresponding file field:

<input name="CustomFile" type="file" />
