Controller:
[HttpGet]
public ActionResult Add(int id)
{
_polAdd = CreatePolicyAddModel(id);
return View(_polAdd);
}
[HttpPost]
public ActionResult Add(IEnumerable<HttpPostedFileBase> files, vmPoliciesAdd model)
{
_policyLogic.AddPolicyFile(files,model.PolicyName,(int)model.SelectedItem, "FILE");
return View();
}
On the post action of controller the colelction is empty, can anyone see an obvious mistake

Naming issue:
<input class="text-box single-line" type="file" name="IT application file" id="IT application file" data-val="true" data-val-required="Please select a file" />
Should of course be:
<input class="text-box single-line" type="file" name="files" id="IT application file" data-val="true" data-val-required="Please select a file" />
So fix your Razor code and make sure you have applied correct name to your file input if you expect the model binder to be able to bind to an action argument called files:
<input class="text-box single-line" type="file" name="files" id="#pick.Name.Trim()" data-val="#pick.IsRequired.ToString().ToLower()" data-val-required="Please select a file" />
Ah an by the way id's cannot contain spaces. So you've got a broken HTML. The following seems wrong: id="#pick.Name.Trim()" as well.
