Unless the user control exposes those events (or exposed the combo box itself, which is a very bad idea) you can't.

That's the whole idea! The internals of a user control are intended to be hidden from the user, and only those priories that the control explicitly exposes are available to code using the control.

You will have to modify the control source to add events which are "passed through" from the combo box to the "outside world".

changes in user control :-

Public Event tbClick() 'As EventHandler

Private Sub cboPaymentOptions_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboPaymentOptions.SelectedIndexChanged
RaiseEvent tbClick()
End Sub

changes in main form :-
'addeded on page load
AddHandler ucPayement.tbClick, AddressOf myfunction

'create a function with name myfunction

public sub myfunction
'do something
end sub
