Your question is not clear. I think you want to handle the event in the parent form rather than raise it from the parent form. Posting your code might help. But here is a general guideline.
To handle user control events in the parent form, hook up the control's event to a method in the parent form like this:
private void Form1_Load(......) {
userControl1.MyEvent+=new EventHandler(UserControl1_MyEvent);
}
private void UserControl1_MyEvent(......) {
}
