title: Split a large winform class
body: <p>I'm using WinForms to design an application. It has many controls (buttons, menus, etc) that have underlying event handlers. I find that my class is getting rather large and hard for one person to navigate. This is due to the fact that each control requires one or more methods to handle events within the context of the window. </p>
  
  <p>What are some techniques for organizing these methods or splitting up such a large class?</p>
