Question

I have a Windows Forms project I’m fixing now in VB.NET.

I need to call RaiseEvent on an event of the parent form in order to route logging to an application calling the parent form.

Similar to this:
RaiseEvent from a UserControl that's placed on a UserControl that's on a Form

But opposite. I need to push an event one level down, rather than bubble it up.

Answer 1

One object cannot raise events that belong to other object.

You should create a Sub in the parent to raise this event for you.

[Parent]

(...)
Friend Sub RaiseMyEvent() 
    RaiseEvent MyEvent(Me,EventArgs.Empty)
End Sub
(...)

[Child]

(...)
parentObject.RaiseMyEvent()
(...)
