背景不想說太多,或者在一年後公開。
現在就是要找出Disable ViewStatus和EventValidation的方法。
EventValidation是ASP.NET authentication module 內的Security control
ViewStatus就是一個節省User重填資料的機制。
ViewStatus 是負責儲起傳送到伺服器的Form Value。
如果ASP.NET 當中有POST BACK,例如登入名稱密碼不正確。
在回到登入介面後,ViewStatus的值會填回Form上。
有錯請指證,小弟不是ASP.NET專家
事件告一段落,簡直如釋重負地想爆炸。
正解︰
EventValidation 只要在 EnableEventValidation set false,就可以消失在Form 中。
不論是在 level、module level、web.config中又可以。
麻煩的是ViewStatus,現實正如官方說明般殘酷。
EnableViewState set 成 false還是會出現在Form中。
大家不要參考override Render method的方法。最後是採納Moving ViewState to the Session Object的方法

Even if EnableViewState is false, the page might contain a hidden view state field that is used by ASP.NET to detect a postback.
