I have a useful framework, written in a different language (PowerBuilder),
which I'd like to replicate in .Net and Forms, but I'm unsure of how to
approach it, as the Event model is being used different between the
development environments.

Currently we have data entry screens, whose columns have been "wired" into a
class that performs checks on the entered data. As the user "leaves" a
column, the specific check / business rule is carried out. A lot of the
checks are common across all the screens and linking the column to the
specific method to be called is as easy a giving the column the appropriate
Name.

How can I create my own framework which would allow an easy method of
connecting / wiring the columns and the method checks together. I was
planning on using DataGrids, but can change that if I need to.
