Silverlight Toolkit DatePicker error indicator

Question

I don't seem to be able to get the red border line error provider for my date picker controls. I'm throwing validation exceptions on the setter of the bound to property as I have with my other controls on the form. I get the error indicator on all my controls on the form but the date picker ones. any help appreciated.

Answer 1

This is a hard one, the Visual States are missing (or were purposely excluded) in controls that were migrated from the Silverlight toolkit
