Clear fields after success
提问by MuriloKunze
I have a page with 2 input type=text..
我有一个带有 2 个输入类型 = 文本的页面。
@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:
在我的控制器中，我这样做：
[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?
所以问题..当我的模型有效时，我将结果设置为“成功”，此时 vm.TalkToUsRequest 为空..但是当页面呈现时，所有字段都具有与我提交时相同的值..甚至我设置 vm.TalkToUsRequest = null!! 如何清除这些字段？

So in this scenario you have to clear your model state if you return back to the same view. Try following:
因此，在这种情况下，如果您返回到同一视图，则必须清除模型状态。尝试以下操作：
ModelState.Clear();
return View(vm);
}

Your answer :
你的答案 ：
TryUpdateModel(yourmodelname);
and it will update your view state
它会更新你的视图状态
and if you also want to clear all Modelstate.error at the same time you can also use :
如果您还想同时清除所有 Modelstate.error，您还可以使用：
ModelState.Clear();
