ModelState.AddModelError on form level with ASP.NET MVC 2 RC

Question

In the previous versions on ASP.NET MVC, you could use ModelState.AddModelError("**_FORM**", "error") to make an error on the form-level instead of a property-level. This seems not to work anymore with the new RC of ASP.NET MVC 2.

Is there another way how to do it? I use <%= Html.ValidationSummary() %> at my View-file...

Answer 1

我个人使用AddModelError("" - 我不知道_FORM来自哪里？ - 并且ValidationSummary()不是黑魔法 - 我使用自己的帮助器，例如，包括特定的（用户特定的）异常消息帮助器很容易编写 - 一个简单的foreach循环遍历ModelState - 所以你可以考虑编写自己的一个。你可以自由地显示表单级别，属性级别或任何你喜欢的东西。

Answer 2

the error are inside modelstate and is send to the helper class of validationsummary by following argument:

this.ViewData.ModelState.Keys

this.ViewData.ModelState.Values
