title: How to assign a click event handler to part of a drawn rectangle?
body: <p>Imagine I use the .NET graphic classes to draw a rectangle.</p>
  
  <p>How could I then assign an event so that if the user clicks a certain point, or a certain point range, something happens (a click event handler)?</p>
  
  <p>I was reading CLR via C# and the event section, and I thought of this scenario from what I had read.</p>
  
  <p>A code example of this would really improve my understanding of events in C#/.NET.</p>
  
  <p>Thanks</p>
