I have a control that includes a property that is an object that has two properties within it, a string and an integer. I'd like this property to be an expandable property at design time in the property grid (like font, location, margins, ect are). I've figured out that I need a TypeConverter for the object and have built that. I figure out that I need to either override the GetPropertiesSupported and GetProperties methods or inherit from ExpandableObjectConverter (I've tried both) to get the parent object to expand into properties.



The problem is that when that property is Nothing (null), I can't expand it. Once I put in some appropriate text, then the plus sign shows up and the object's properties are expandable and shown. It is very likely something stupid, but how do I get the property to be expandable when the property is Nothing (null)?



Thanks!
