Make sure there is an event declaration in the conrol:
Public Event BubbleUpRegister As EventHandler(Of EventArgs)
Add handler:
Protected Sub RegisterUnit1_BubbleUpRegister(ByVal sender As Object, ByVal e
As System.EventArgs) Handles RegisterUnit1.BubbleUpRegister
If this does not work, the control is likely NOT declared using WithEvents.
