How can I add a control to a parent form, in design time, through a custom component?

[Simonetos The Greek]

I have create a custom component which changes some properties of it's parent form when placed in design time. But I also want this component, in design time again, to add some controls to it's parent form. I tried something like this code example below, but with no luck. The added control placed on the form, but I can't select it, just stands there!!! Any idea what exactly am I doing wrong? Thank you in advance!!!

Public Class MyCustomComponent
     Private _MyControl As New MyUserControl
     
     '...Rest of my code
     
     Private Sub OnPlace()
           '...Rest of my code
          _ParentForm.Controls.Add(_MyControl)
     End Sub

     Private Sub OnDispose()
           '...Rest of my code
          _MyControl.Dispose()
    End Sub

End Class
