Wow, I'm really surprised that Joel Spolsky of all people would say
this - and so recently too.
I used to like System 7's Balloon Help approach - grey out the menu
but the help balloon would explain why it wasn't available (at least
in an app that took the trouble to implement this). Sadly, as with
many things since hen, in some ways we've gone backwards.

The preferred way to do this is to prevent the user clicking the
button if it's not appropriate by greying it out.
This is far more user-friendly than rebuking a user for having the
audacity to click your button when they shouldn't have, even though
they had no visual cue that they shouldn't. The "permit then
rebuke" form of input validation is the hallmark of bad UI design.
Sadly, it's all too common.

I've set up matrix with 2 radio buttons (1 and 2) with a delegate
method that gets run when the matrix gets clicked. Lets say radio
button 1 is highlighted and someone clicks on radio button 2. The
delegate method has some code that checks whether the radio
buttons are allowed to be changed from 1 to 2 and if not, sends an
alert to the user.
My problem is how can I stop the radio buttons themselves changing
from 1 to 2. When programming in Visual Basic there was a method
that stopped the action from completing. Is there something
similar I can do here or some other way.
