Hi foleyp,
Yes, I meant DomainType.
So all a domaintype does is specify that the property is of a type defined in regular code. its then down to the standard .Net mechanisms for that class to get it to display in the property grid the way you'd want it.
This usually comes down to using attributes to set type convertor etc. You can find lots of information on this by searching MSDN/the web for topics like "Adding Design-Time support to your control"
