I'm working on a project where a customer needs some custom controls.  One of the requirements is to have a UserControl contain a TextBox and a Button and to expose an event that will be raised when the button is clicked.  Easy enough, but to enhance the design time experience instead of adding a ButtonClick event for example, I added the following to the UserControl

public new event EventHandler Click
{
   add
   {
      lock (m_button)
      {
         m_button.Click += value;
      }
   }
   remove
   {
      lock (m_button)
      {
         m_button.Click -= value;
      }
   }
}

What this does is instead of adding the EventHandler to the UserControl.Click event, I add it straight to the m_button.Click event.  Not terribly complicated but gives a better design time experience and avoids creating a new event to expose.
