Allow complex type property to be expanded without ExpandableObject attribute


I have looked into the source code and can see how DescriptorPropertyDefinition.ComputeExplandableAttribute works, but unfortunately this class is all internal so I cannot modify it to use an "unobtrusive" approach to property expansion.

In my opinion its better to first have a way to accomplish something without adding an intrusive attribute, because adding an attribute requires you to own the code of the type you are inspecting. This is often not the case.

I agree! Down with view-DLL attributes being required in model code!!!!

Here's a patch. It's quick and hacky, but I don't care...

This will be fixed in v3.3 Plus, with a better fix.

Will the fix also be available through 3.3. community edition?

Also when are you moving to GitHub? :)

No, the fix is only available in the Plus versions of the Toolkit (v3.3 Plus and up).
GitHub is not a priority for now, but could be eventually.
