I am running into a weird problem with windows server 2008 R2. I have WPF app which has virtualization enabled (virtualization stack panel and lazy loading for the tree view). It works as exepcted on windows 7 system. However on a windows 2008 R2 system with the classic wndows theme(no aero aka destop experiance turned off), it does not. When I debug it the controls private properties indicate that virtualization is enabled, however my I see that all the data is fetched through my virtualized model.
EDIT: Enabled user experiance etc but not the windwos7 theme still the issues persists. This is on a TreeView control. I use thsi technique to enable data virtualization: http://www.codeproject.com/KB/WPF/WpfDataVirtualization.aspx
Any ideas as to what could be going on
WPF uses hardware acceleration to perform the rendering. You lose functionality whenever this is not present. Are you connecting to the server via Remote Desktop or with a direct console?
