User Control, can we add event in the property panel?

Question

创建用户控件（使用c＃winforms）后，是否可以创建一个可以从属性面板（在设计时）和其他默认控件一样访问的事件？

Answer 1

Yes. For example, within the class definition in the UserControl's .cs file, add the line:

public event EventHandler MyNewEvent;

At design time, in a form or control that contains an instance of your UserControl, you should be able to select the control and find the MyNewEvent entry in the properties panel.

Answer 2

Add Browsable argument to your event definition:

[Browsable(true)]    
public event EventHandler MyNewEvent;
