ASP.NET MVC 4：如何从提交表单上的视图更新模型

Question

I create some form and I need to assign field CreationDate on submit form:

@model Namespaces.Chapter

@using (Html.BeginForm ()) {
    <p>Title: @Html.TextBoxFor(c => c.Title)</p>
    ...
    @{ Model.CreationDate = DateTime.Now;} <- somehow like that, but this code does not works
    <input type="submit" value="Submit" />
}

How to do that?

Answer 1

You have to do this in the controller action before passing it to data access like:

public ActionResult SomeAction(SomeClass obj)
{
   obj.CreationDate = DateTime.Now;

   // your business logic goes here
