MVC 1 IsValid属性等效于视图端的ModelState.IsValid

Question

我正在尝试在发生错误时显示某个div。我在控制器端添加错误，我试图调用ViewPage的IsValid属性，并出现了这个错误：

Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation=True and initiated the postback, or after a call to Page.Validate.

有没有办法轻松验证？

好吧......忘了吧。

我刚刚发现它：

ViewData.ModelState.IsValid
