Thanks for the advice!
The problem is that it is only during the conversion that I know if the
string was valid or not. It's a bit complicated to explain here because
it is part of the problem domain. The pseudocode is like this:
recieve input
parse input
if exception is thrown
input was invalid
else
input was valid
So, I cannot pre-validate the string as you suggest unless I run the
same procedure above twice, which is not something I want to do.
The problem I am facing with IConverter is that the converter throws an
exception rather than signaling an invalid state.
I could return some kind of "invalid" value or "null" or something, but
I would lose all the benefits of validation (feedback messages and so
on).
Any ideas about how I could get around this problem, or at least
something better than return null from IConverter?
Thanks!
Dave
