Create your event on the UserControl:
在 上创建您的活动UserControl：
Public Class UserControl1
Public Event UC_Button1Click()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent UC_Button1Click()
End Sub
End Class
And then use the new event:
然后使用新事件：
AddHandler userControl1.UC_Button1Click, AddressOf Button1_Click
Or you can simply define it like this on the UserControland access to it from outside (not recommended):
或者你可以简单地定义它UserControl并从外部访问它（不推荐）：
Public WithEvents Button1 As System.Windows.Forms.Button
And then:
进而：
AddHandler uc.Button1.Click, AddressOf Button1_Click
