从.NET C#中的用户控件引发父窗口上的事件 [英] Raising an event on parent window from a user control in .NET C#

问题描述

标题几乎可以解释这个问题.首次运行该应用程序时，我已将一个用户控件加载到主窗口中.我想做的是单击用户控件上的按钮时在父窗口上引发事件，那么如何从用户控件上的button1_Click引发父事件?

The title pretty much explains the question. I have a user control loaded into the main window when the application is first run. What I want to do is to raise an event on parent window when a button on the user control is clicked, so how can I raise a parent event from button1_Click on the user control?
