以下代码的问题是当我点击“提交”按钮时，我希望它可以将我从查看页面带回控制器。我在控制器方法[HttpPost] ProductEdit中设置了一个断点，它永远不会停在那里。MVC查看页面提交不回控制器
The view generate the code :
<form method="post" action="/Home/ProductEdit?ProductId=4" novalidate="novalidate">
<input type="submit" value="Submit">
请帮我找出原因，并提供详细的代码来解决它。
public class ProductEditViewModel : Product
{
// For DropDownListFor need IEnumerable<SelectListItem>
public IEnumerable<SelectListItem> SupplierItems { get; set; }
// For RadioButtonFor need below
public Int32? CategorySelectedId { get; set; }
public IEnumerable<Category> CategorieItems { get; set; }

退房页面上的HTML并验证<形式行动=点到家庭/ productEdit，而且方法是后。 – 2014-08-28 15:53:22
您没有明确指定表单应该提交到哪里（'@using（Html.BeginForm（））'），所以在这种情况下它会提交给调用方法'/ Home/Index'。 – 2014-08-28 15:59:52
您能否为您的代码提供ProductEditViewModel的定义，并解释提交表单时会发生什么？它会把你带到不同的行动吗？ – 2014-08-28 15:59:54
