RadRotator enables the left arrrow even though the InitialItemIndex is zero and WrapFrames is false. Logically, you can't go one page before the first item, yet RadRotator allows you to do that. What's even worse - when users click the left arrow the RadRotator silently loads third page and then locks up the users between first three pages that are even loaded in the reverse order (this is experienced with version 2012.1.215).
RadRotator also enabled the right arrow even though it does not know whether there are further items on the next page. And when users click that "Page Next" button one of two things happen - either the arrow gets disabled to mark that there is no more items (why RadRotator didn't find this out earlier? Isn't it missing a GetCount() method?) or it goes to next page and then again locks up users there and they cannot click on the "Previous Page" button.
This happens slightly randomly, unfortunately, but often enough to confuse and scary users.
I believe this could be solved by preloading the first page not on demand but while page render. At this moment the RadRotator could be told the total number of items so it would behave properly when paging. I tried to fill the Items set of RadRotator from code behind and later turn on the load on demand but the RadRotator renders empty.
Can you please suggest a way of prefilling the first page from code behind and let the other pages be loaded on demand?
