Question

I have a page with 2 input type=text..

@model MVC3.ViewModel.TalkToUsVM

@using (Html.BeginForm())
{
    <ul>
        <li>@Html.TextBoxFor(m => m.TalkToUsRequest.Name)</li>
        <li>@Html.TextBoxFor(m => m.TalkToUsRequest.Email)</li>
    </ul>

    <input type="submit" value="Save"/>
}

in my controller I do this:

[HttpPost]
public ActionResult Create(TalkToUsRequest talkToUsRequest)
{
    var vm = new TalkToUsVM();

    if (TryValidateModel(talkToUsRequest))
    {
        vm.Result = "Success";

        return View("Create",vm);
    }

    vm = new TalkToUsVM
    {
        Result = "Errrooooooor",
        TalkToUsRequest = talkToUsRequest
    };

    return View(vm);
}

so the problem.. when my model is valid, I set the result to “Success” and in this point vm.TalkToUsRequest is null.. but when page is rendered, all fields are with the same value that when I submited.. even I setting vm.TalkToUsRequest = null!!
How can I clear this fields?

Answer 1

So in this scenario you have to clear your model state if you return back to the same view.
Try following:

    ModelState.Clear();
    return View(vm);
}
