Question

I don’t like to have to use parameters to my POST action methods in addition to my view model parameter. However, for a file upload using the Telerik Upload helper, it seems I am forced to do this. The posted value is IEnumerable<HttpPostedFileBase>. Is there any way I can also bind this to the model without the effort of custom model binding.

Answer 1

I don’t like to have to use parameters
to my POST action methods in addition
to my view model parameter.

Me neither. That’s why I use view models:

public class MyViewModel
{
    public IEnumerable<HttpPostedFileBase> Files { get; set; }
    public string Foo { get; set; }
    public string Bar { get; set; }
    ...
}

and then:

[HttpPost]
public ActionResult Upload(MyViewModel model)
{
    if (!ModelState.IsValid)
    {
        return View(model);
    }

    if (model.Files != null)
    {
        foreach (var file in model.Files)
        {
            if (file != null && file.ContentLength > 0)
            {
                // process the uploaded file
            }
        }
    }
    ...
}
