You need to add the csAcceptsControls style to your control's ControlStyle property. Something like this in the constructor of your control class:

  ControlStyle := ControlStyle + [csAcceptsControls];

You will almost certainly want to set other ControlStyle properties also though so don't just take this verbatim but research the ControlStyle flags and decide which are appropriate in your case.
