The Initialize event is raised before the form is completly loaded (somewhere between the Form_Initialize and Form_Load event). You cannot reference to the parent at this time.

Also, I would like to say that it is a very poor design to reference a public variable from a component. Your component must be completly isolated from the applications that use them to be usefull and easy to re-use.
