AdCreated 事件

每次顯示廣告時發生。

public event AdCreatedEventHandler AdCreated

備註

事件處理常式接收包含所顯示的廣告屬性的 AdCreatedEventArgs 屬性。下表顯示提供此事件特有資訊的屬性。

屬性	說明
AdProperties	傳回包含引發 OnAdCreated 事件後從 XML 檔案擷取之所有廣告屬性的字典。
AlternateText	指定要呈現在 AdRotator 控制項中的替代文字和工具提示 (如果瀏覽器支援)。
ImageUrl	指定要呈現在 AdRotator 控制項中的影像。
NavigateURL	指定當按一下廣告時瀏覽器巡覽的 URL 參考。

如果設定 AdvertisementFile 屬性，則會在已從檔案選取廣告後發生此事件。

範例

下列範例示範如何截獲 AdCreated 事件以決定使用者是否選取預設廣告。
