Validation Groups in ASP.NET 1.1
So in ASP.NET 2.0 you can have validation groups so one set of fields can be validated when a certain button is clicked and another set of fields on the same page can be validated when another button is clicked. I don't find myself needing this too often, but this is fantastic for when I do need it. However, I've recently found a place in one of our applications where we needed it and we're using ASP.NET 1.1. How to get around it?
This gem of an article describes a kind of cool rig for faking validation groups yourself. It unfortunately will only work server-side and not client-side, but at least it's possible.
