備註

RegisterViewStateHandler方法會HtmlForm透過伺服器控制項自動呼叫。The RegisterViewStateHandler method is automatically called through the HtmlForm server control. 如果未叫用此方法,將不會保存網頁檢視狀態。If this method is not invoked, the page view state will not be persisted.

注意

一般而言,只有頁面HtmlForm的伺服器控制項才會呼叫這個方法。Typically, only the HtmlForm server control for the page calls this method.
