Did you try to Google for the that? There are plenty of samples.

Please see this, quote good one:
http://codeblitz.wordpress.com/2009/05/08/wpf-validation-made-easy-with-idataerrorinfo/[^].

That one was for WPF (why, why din''t you tag the library you want to use?! Just to force me into doing double work?).

This is for System.Windows.Forms:

Please do yourself and all of use a favor: work at your Google skills.

Good luck,
