title: Customizing the behavior of ControlDesigners for Controls derived from native .NET controls
body: <p>My question is related to this question:
  <a href="https://stackoverflow.com/questions/93541/baseline-snaplines-in-custom-winforms-controls">Baseline snaplines in custom Winforms controls</a></p>
  
  <p>However, in my case, I have created a new control that <code>derives</code> from TextBox rather than <code>containing</code> a TextBox.  I would like to have a custom ControlDesigner, but I would like to modify the behavior of the TextBox's designer rather than having to write a complete designer myself.  In particular, I'd like to be able to return the TextBox's SnapLines while providing some custom verbs.  Is there a good way to do this?</p>
  
  <p>EDIT: To clarify, this is for Windows Forms in .NET 2.0.</p>
