Hello Telerik Team,
We are usign Telerik Controls for Silverlight (version 2012.2.1015.1050) and having a problem when use really "big" RadDocument controls. For testing I created a RadDocument object and started adding new fragments so the number of pages grows. I noticed that the exception 'System.OutOfMemoryException' is thrown when number of pages between 500 and 600 in a RadDocument object. It depends on a CPU of course. However, it is a serious issue for us, because we need to display documents with more than 1000 pages sometimes. I don't know whether this is a bug or limitation of Silverlight, but maybe it has been solved in new versions of Telerik Controls for Silverlight?
