Enter event not firing in Panel inside a UserControl

I added a Panel inside a UserControl i design time.

Then, I added this control to a form.

I want to show a focus dashed border when the control has the focus.

Unfortunately, the Enter event from the panel never fires. I only get a fire when I click on the user control itself.

To extend this question. How can I forward events from controls inside a user control to the base user control? A comment from Hans Passant in this question says that by default events are forwarded to their direct parent. I didn't change any of the control's properties. What am I doing wrong? Is there an obvious property I need to change on each control i order to force it to forward unhandled events?

I am using DevExpress controls but this behavior is same in windows WinForms controls.

edit: I understand that panel might not be able to get focus. If this is true, how do I forward each mouse event to the parent control?

Use panel1.Select() on MouseClick event of the panel and you will be able to trigger panel1.Enter and panel1.Leave

Based on your comment, from inside your UserControl, handle the panel's MouseDown event and set the focus to the parent control:

public UserControl1() {
  InitializeComponent();
  panel1.MouseDown += new MouseEventHandler(panel1_MouseDown);
}

void panel1_MouseDown(object sender, MouseEventArgs e) {
  if (!this.Focused)
    this.Focus();
}
