I'm getting a stack trace much like the one above when I scroll rapidly to the end of a RadDataBoundListBox while it is waiting for new data (my data comes in via web service). It seems like, when I hit the bottom of the list scrolling quickly enough, in doing the bounce past the "Loading" content, it hits the extreme of the bounce animation and then blows up with the ArgumentOutOfRange indexing a List<RadVirtualizingDataControlItem>.
Since there was mention of a reported bug on this, I tried upgrading to the latest version of Q3 (2011.3.1116.2040) but am still having the problem. I also tried switching to another paradigm, the Rad virtual collection, but then I got bunches of the "loading" content over and over.
I'm looking for a relatively quick fix as I'm otherwise ready to release this app.
Thanks in advance for any help you can provide.
