Page.OnPreRenderComplete(EventArgs) Page.OnPreRenderComplete(EventArgs) Page.OnPreRenderComplete(EventArgs) Page.OnPreRenderComplete(EventArgs) Method

定義

PreRenderComplete 事件之後,並在呈現頁面之前,引發 OnPreRenderComplete(EventArgs) 事件。Raises the PreRenderComplete event after the OnPreRenderComplete(EventArgs) event and before the page is rendered.

protected:
 virtual void OnPreRenderComplete(EventArgs ^ e);
protected virtual void OnPreRenderComplete (EventArgs e);
abstract member OnPreRenderComplete : EventArgs -> unit
override this.OnPreRenderComplete : EventArgs -> unit
Protected Overridable Sub OnPreRenderComplete (e As EventArgs)

參數

e
EventArgs EventArgs EventArgs EventArgs

包含事件資料的 EventArgsAn EventArgs that contains the event data.

備註

OnPreRenderComplete方法在網頁生命週期的預先呈現階段完成時呼叫。The OnPreRenderComplete method is called when the prerendering stage of the page life cycle is complete. 在頁面生命週期的這個階段,會建立所有控制項,而該頁面已準備好要呈現的輸出。At this stage of the page life cycle, all controls are created and the page is ready to render the output.

這是呼叫頁面的檢視狀態儲存之前的最後一個事件。This is the last event called before the page's view state is saved.

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊,請參閱 < 處理和引發事件For more information, see Handling and Raising Events.

OnPreRenderComplete 方法也允許衍生類別處理事件,而不用附加委派。The OnPreRenderComplete method also allows derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

當在衍生類別中覆寫 OnPreRenderComplete(EventArgs) 時,請確定呼叫基底類別的 OnPreRenderComplete(EventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnPreRenderComplete(EventArgs) in a derived class, be sure to call the base class's OnPreRenderComplete(EventArgs) method so that registered delegates receive the event.
