AdCreatedEventArgs 类

  • 项目

为 AdRotator 控件的 AdCreated 事件提供数据。无法继承此类。

**命名空间:**System.Web.UI.WebControls
**程序集:**System.Web（在 system.web.dll 中）

语法

声明
Public Class AdCreatedEventArgs
    Inherits EventArgs
用法
Dim instance As AdCreatedEventArgs

public class AdCreatedEventArgs : EventArgs

public ref class AdCreatedEventArgs : public EventArgs

public class AdCreatedEventArgs extends EventArgs

public class AdCreatedEventArgs extends EventArgs

备注

当 AdRotator 控件在页面上显示广告时，引发 AdCreated 事件。

示例

下面的代码示例演示如何为 AdCreated 事件指定和编写处理程序。它在 AdRotator 控件创建后获取与公布关联的 URL，并将该 URL 显示在此控件下面。本示例需要下面的示例中列出的 XML 文件 (Ads.xml)。
