Catching SelectedIndexChanged event from ListBox in UserControl added at run time in VB.NET

Hello. I have a standard listbox inside standard usercontrol. Data source of listbox is a collection of class with 2 fields created for Display and Member values. I add instance of this control at run time:

Private Sub Customers_Load(sender as object, e as EventArgs) handles MyBase.Load

dim ctl as new ctlCustomers

Panel1.Controls.Add(ctl)

Add Sub

This control can be added from different forms like in <Customers_Load>

 I am looking for standard way to catch event SelectedIndexChanged of listbox from different parent forms and pass parameter of selected valuemember

Thank you

Michael
