推荐答案

做到这一点的最佳方法是在控件和hte页面之间连接一个委托，以便控件可以向该页面发送消息.一种更硬编码的方法，其中控件需要知道包含它的页面的详细信息，这表明您的页面设计已损坏，并且您的控件实际上不值得编写为控件，它应该只存在于页面中

The best way to do this is to hook up a delegate between the control and hte page, so that the control can send a message to the page. A more hard coded approach, where the control needs to know the specifics of the page that contains it, is a sign that your page design is broken, and your control is not really worth writing as a control, it should just live in the page, or be better engineered.

为此，一种方法是在app_code文件夹中创建一个抽象类，该类必须具有抽象方法.通过此类继承您的页面并覆盖该方法.您可以在usercontrol中访问的方法.

例如，请查看链接

For that, one way is create an abstract class in app_code folder, which must have an abstract method.Inherit your page by this class and override the method.This method you can access in usercontrol.

For example , have a look to the Link
