Events not firing in VS2008

I have used data binding in the past, but always with my own biz
objects, not with a Data Adapter. I am now using the Microsoft SQL
Embedded in this Mulch Order Entry program I am writing for my son's
boy scout troop. What I cannot figure out is why, after wiring up the
Data Binding, the events on the Exit button and the red X (upper right
of the dialog) will not fire and close the form. The project is a
VS2008 project and the source code can be found here:
