Validation controls

[Brian Nantz]

Does anyone know if there are Validation contorls like these:

http://www.dotnetmasters.com/Samples.htm

for CF? I try porting these but there is too much missing in the CF to
get this functionality. I am not sure this is even a good solution for
smartphone but PPC should be OK. But the idea of user feedback on
invlaid input is very important.

Thanks for the help.

A simple way to make up for the missing ErrorProvider class is setting
the control's BackColor property to red if not valid, and back to it's
original color on the next (Text)Change (using it's Changed event).

At least in .NET CF 1.0 it seems that Validating / Validated is not
properly fired when leaving a form (e.g. calling Hide) but you can fix
this using the form's Closing event.
