Hi,
I'm looking at my application and the QSF demos, and am seeing a similar thing happening with RadCarousel. When you scroll into selection the item on either side of a RadCarousel, it correctly looks focused and selected. However, on either end of the RadCarousel, you can scroll beyond the last item. On the Carousel/First Look demo (WPF Q1 2009 SP2), you can scroll three extra notches to the left of "Ann Devon" and three extra notches to the right of "Ana Trujillo." Thus it seems like there are six "ghost items" in the carousel. I'm sure you have noticed this, since it is in the QSF itself. However, I'm wondering, is there any way to disable this in my own RadCarousel (a property or something)? Personally I think it looks a little weird to be able to scroll past either end of the list of items. I'd love it if anybody could help me out getting rid of these ghost items!
Also, there's a bit of a quirk with these ghost items - I'm looking again at the Carousel/First Look example. When an extrememost item is selected (in this case, Ann Devon or Ana Trujillo) by (single or double) clicking on it, scroll out into the ghost items. You now cannot double click the extrememost item to bring that item in front and in focus. Now scroll back and (single/double) click on either Georg Pipps or Christina Berglund to bring them front and center. Now, without clicking on other items (i.e., use the scroll wheel on the mouse or the scroll buttons on the carousel), scroll out to the ghost items (this is, of course, the only way to scroll out into the ghost items, using the mouse or the buttons). You will now be able to double click on one of the extrememost items and zoom back into the regular items list. Sorry if my instructions to replicate this are a little foggy... you may need to scroll as far left or as far right into the ghost items as possible in order to see these effects. However, even if this is a little unclear, it is totally happening every time on my machine and is just a little bit of a bug I think. I hope it's not just me! :)
Thanks,
UIdev

Hi UIdev,
We were unable to reproduce the ghost items problem. Could you provide us with more information so that we can fix the problem that you are experiencing? How do you scroll beyond the last item? Do you use the keyboard, the navigation buttons or any other method?
Thank you for your feedback and I hope we will be able to resolve the issue as fast as possible.
Best wishes,

Hi Milan,
I created a support ticket with a video of what I'm describing. In the video I scroll beyond either end of the items in the list (first paragraph of my previous post) and demonstrate how that affects the ability to double-click your way back into the list (second paragraph of my previous post). To scroll into the "ghost items," you can just do this:
-Open up the Carousel/First Look example in the QSF.
-Scroll to the right (you can just use the horizontal navigation buttons) until you reach the next-to-last contact card in the list. That card should look front and centered and should be the biggest and most opaque card.
-Scroll one item to the right, reaching the rightmost item in the list. Now, as expected, this contact card gains focus.
-Now scroll one "item" to the right again using the horizontal navigation buttons. You no longer bring any item into focus (hence my idea that you are bringing some "ghost item" into focus). The rightmost item in the list, while it still may appear the biggest relative to the other visible items, is not as big or opaque as it was in the previous view.
Do you see how the leftmost/rightmost item can be brought into focus, but then lose focus in this manner? It's in the video I put in my support ticket if you can't replicate it. Let me know if there is any workaround. What I'm looking to do is have the most you can scroll to be when the rightmost/leftmost item is in focus. I hope this is clear as well - I think the video should clear things up a bit!
Thanks very much for your help,
UIdev

I've found out, that the count of ghost items is in dependany with the ItemsPerPage-Property. There are approximately 1/2 Ghost items then ItemsPerPage.
