RepeaterCommandEventArgs 类

  • 项目

为 Repeater 的 ItemCommand 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 RepeaterCommandEventArgs
    Inherits CommandEventArgs
用法
Dim instance As RepeaterCommandEventArgs

public class RepeaterCommandEventArgs : CommandEventArgs

public ref class RepeaterCommandEventArgs : public CommandEventArgs

public class RepeaterCommandEventArgs extends CommandEventArgs

public class RepeaterCommandEventArgs extends CommandEventArgs

备注

有关 RepeaterCommandEventArgs 的实例的初始属性值列表，请参见 RepeaterCommandEventArgs 构造函数。有关处理事件的更多信息，请参见 使用事件。

示例

下面的示例说明一种处理 Repeater 的 ItemCommand 事件的办法。只要单击 Repeater 中的 Button 控件，便会显示有关该按钮的信息。
