MVC3 View doesn`t display empty form on validation passed

Question

Very simple situation, here is my model: ``` public class Comment { [Required] public string Name { get; set; } [Required] public string Text { get; set; } } ``` Here is my controller: ``` public class CommentController : Controller { // // GET: /Comment/Create public ActionResult Create() { return View(); } // // POST: /Comment/Create [HttpPost] public ActionResult Create(FormCollection collection) { Comment new_comment = new Comment(); if (TryUpdateModel(new_comment)) { return View(new Comment()); //problem is there } else { return View(new_comment); } } } ``` And here is my standart genered strongly-typed View: ``` @model test.Models.Comment @{ ViewBag.Title = "Create"; }

Create

@using (Html.BeginForm()) { @Html.ValidationSummary(true)

Comment <…

Accepted Answer

Clear the modelstate:

```
if (TryUpdateModel(new_comment))
{
    ModelState.Clear();
    return View(new Comment()); //no more problem here
}
```

All HTML helpers first look at the ModelState when rendering their values and only after that in the model.

Or even better and more properly use the Redirect-After-Post pattern (i.e. redirect after a successful POST):

```
if (TryUpdateModel(new_comment))
{
    return RedirectToAction("Create");
}
```
