Edit Question
Title
Body
I have a DataGrid, populated with objects in an ArrayCollection. After updating one of the objects' fields, I want the screen to update. The data source is not bindable, because I'm constructing it at runtime (and I don't understand how to make it bindable on the fly yet -- that's another question). In this situation, if I call InvalidateDisplayList() on the grid nothing seems to happen. But if I call invalidateList(), the updates happen. (And it's very smooth too -- no flicker like I would expect from invalidating a window in WIN32.) So the question: what is the difference between InvalidateList and InvalidateDisplayList? From the documentation it seems like either one should work.
