We use the AutoGeneratingPropertyDefinition hook in a RadPropertyGrid to specify templates for the various properties we expose. For a collection exposed in this property grid, CollectionEditor seems like a great model, but is there any sort of comparable mechanism to override or specify the property definitions that then appear in the CollectionEditor? I don't see anything that looks immediately obvious in CollectionEditor or CollectionEditorPicker, and the CollectionEditor that ends up in our RadPropertyGrid doesn't seem to hit the property grid's AutoGeneratingPropertyDefinition event handler.
Elsewhere in these forums, I see suggestions to override the complete Template of CollectionEditor; is that the only option in this case? Are there any better/easier methods to specify DataTemplates for properties in a CollecitonEditor?
