Stumbled across something i cant really see where the problem is.
So i created a dead simple contact form (hardcoded, single purpose only), that takes a few inputs from the user and sends an email. The fields are validated with plain old "RequiredFieldValidator" and others.
When adding the usercontrol to a standard webform aspx page in my visual studio project, everything works fine, emails works, and validators work. I have taken great care to be sure everything is wired up correctly, and with proper validation groups etc.
I then added the usercontrol to my umbraco site, the control is displayed fine but the validation does not fire and isnt shown at all.
I dont think its necessary to show any code as there isnt much to show, its all fairly simple and straight forward.
So anyone stumbled across the same problems?
