Is there a HTMLHelper for file upload? Specifically, I am looking for a replace of
using ASP.NET
Improved version of Paulius Zaliaduonis' answer:
In order to make the validation work properly I had to change the Model to:
public class ViewModel
{
public HttpPostedFileBase File { get; set; }
[Required(ErrorMessage="A header image is required"), FileExtensions(ErrorMessage = "Please upload an image file.")]
public string FileName
{
get
{
if (File != null)
return File.FileName;
else
return String.Empty;
}
}
}
and the view to:
@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new
{ enctype = "multipart/form-data" }))
{
@Html.TextBoxFor(m => m.File, new { type = "file" })
@Html.ValidationMessageFor(m => m.FileName)
}
This is required because what @Serj Sagan wrote about FileExtension attribute working only with strings.
