推荐答案

1)如果您想对按钮做出反应，请在用户控件中单击，然后使用页面的click事件将点击传播给用户控件.

2)如果要基于用户控件中发生的事情来设置按钮的状态，那么最好的选择是处理来自父控件可以使用的用户控件中的自定义事件，或者如果这是一个回发事件，公开一个或两个属性以在页面中获取相关信息并处理该级别的按钮.

用户控件绝不应尝试直接在父页面上进行修改.

1) If you want to react to the button click in the user control, then use the click event of the page to propogate the click to the user control.

2) If you want to set the state of the button based on something that happens in the user control, then your best bet would be to handle a custom event from the user control that can be consumed by the parent page, or if this is a postback event, expose a property or two to get information in the page that is relevant and deal with the button at that level.

At no time should the usercontrol be attempting to modify something on the parent page directly.
