As I was looking over the validation controls in Genghis I kept thinking that the ValidationSummary control that we have in ASP.NET was missing.  Michael Weinhardt has a series of articles on MSDN from last year that overviews how to create a ValidationSummary for WinForms. I’m wondering why this hasn’t been incorporated into Genghis? Anyway the articles are here:
