Design-Time Validation for positive integers

[Nathan Sokalski]

I have several properties in my custom control that I only want to allow
positive values for. Because the unsigned integral types (such as UInteger,
UShort, etc.) are not CLS compliant, it gives an error when run. Is there a
way to validate that only positive values were entered if I use the signed
types? Thanks.

Create your own class of validated positive integer, and create a custom
converter for the type. The custom converter can return 'invalid' for any
string that would convert to a negative integer.
