The standard Silverlight date/time editors throw a validation "Input is not in the correct format." when changed to null (blanked out). The RadDateTimePicker uses a nullable SelectedValue and that validation message is never displayed. The property is a stright up DateTime and has a RequiredValueVerifier (DevForce) but nothing is ever shown in the UI that the field needs something done to become valid. The RequiredValueVerifier is never actually used in the standard Silverlight controls because I believe it hits a cast or parse exception first.

How do I show in the UI that the field is required?

Thanks,
Steve

Thanks Ivo,

The one that made it work was ValidatesOnExceptions=True, which you didn't have in the sample.

Thanks,
Steve
