Question

I’m building a validation form in my application. In that form there are two buttons. One to accept and one to reject. When the user press reject the rejection reason field must be provided. I check this serverside.
I first check what button is pressed and then if the field is empty I add a moddel error to the modelstate. But, because all fields in the form are readonly, those are not posted back to the server and therefor when I return the view back to usern there is no data. I’m probably missing something obvious, but cant find what to do. (I know I can make all fields in my form hidden, but due to the large amount of fields this would be really ugly)

This is my code.

    [HttpPost]
    public virtual ActionResult Validate(string action, Record dto) {

        if(action == Global.Accept) {
            ciService.Store(dto);
            return RedirectToAction("Index", "Ci");
        } else {
            if(string.IsNullOrEmpty(dto.RejectionReason)) {
                ModelState.AddModelError("RejectionReason", "REQUIRED!!!!");
                return View("Validate", dto);


            }
            ciService.Reject(dto);
            return RedirectToAction("Index", "Ci");
        }
    }

You need to recreate the model from the database and then change it to match whatever changes are posted in dto. Then use that combined model in the view.
