Expose collection items into PropertyGrid

Hi David,

I'm not sure that is possible, at least using the built-in mechanisms.  The problem is that a property model is created for the collection and that is what watches for collection changes, so it knows when the refresh the children.  If you take that collection property model out of the UI, then you also lose the property models for the child items, since they are nested within that parent property model.

The PropertyGridCustomDataFactory QuickStart is an example of merging together property models so that properties from a couple hierarchy levels are altered in how they appear.  That is similar to the concept you’re trying to achieve, but without the collection scenario.  If you want to use that kind of mechanism, you’d have to watch for collection changes on your own and update the property models appropriately when appropriate.
