表示處理 DayRender 控制項之 Calendar 事件的方法。

public delegate void DayRenderEventHandler(System::Object ^ sender, DayRenderEventArgs ^ e);

public delegate void DayRenderEventHandler(object sender, DayRenderEventArgs e);

type DayRenderEventHandler = delegate of obj * DayRenderEventArgs -> unit

Public Delegate Sub DayRenderEventHandler(sender As Object, e As DayRenderEventArgs)

參數

sender: Object

事件的來源。

e: DayRenderEventArgs

DayRenderEventArgs，其中包含事件資料。

範例

下列程式碼範例示範如何指定和撰寫事件的處理常式 DayRender ，使顯示月份中的天數背景色彩變成黃色。它也會示範如何將控制項新增 System.Web.UI.LiteralControl 至儲存格，來自訂儲存格的內容。

備註

雖然控制項不支援 Calendar 資料系結，但可以修改個別日期儲存格的內容和格式設定。 Calendar在控制項顯示在網頁上之前，它會建立並組合組成控制項的元件。建立 DayRender 控制項中的每個 Calendar 日期資料格時，就會引發事件。您可以在事件事件處理常式 DayRender 中提供程式碼，來控制日期儲存格的內容和格式設定。如需自訂日期儲存格內容的詳細資訊，請參閱 OnDayRender 。

建立 DayRenderEventHandler 委派時，必須識別處理事件的方法。若要使事件與您的事件處理常式產生關聯，請將委派的執行個體 (Instance) 加入至事件。除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。如需事件處理常式委派的詳細資訊，請參閱處理和引發事件。
