After the last update I did for my telerik products I started getting error reports from my user base. I didn't change anything to do with the carousel on my last release. I am attaching the error in a png file, let me know if anyone has any ideas. I have also had a long standing issue with the carousel where I change the selected item from code behind and if I have more than 5 items in the carousel, the third item will be brought to the top instead of the selected item. I do have code that I use to make sure that the items stay in view. But I can't see why the carousel is changing position, I had to set my selected item to null and then to the value I wanted it to be. So the carousel changes to the third item in the list then after setting it to null and back to my item it will select it properly.
